 ## [Unreleased]
 ### Added
-_No unreleased changes yet_
+- **Web documentation portal**: All 13 user guides are now accessible at `/help` directly in the app — no need to navigate to GitHub. A guide index lists every guide with a description; each guide page renders full markdown with heading anchors for deep linking.
+- **In-guide table of contents**: Each guide page displays a sidebar with an auto-generated "On This Page" section linking to all headings in the current guide. Collapses to a hamburger toggle on mobile.
+- **Contextual help links**: Small help icons throughout the build wizard, bracket selector, owned cards mode, partner selection, and other UI areas link directly to the relevant guide section in a new tab — without interrupting the current workflow.
+- **Documentation: Multi-Copy Package guide**: New dedicated guide covers all multi-copy card archetypes, count recommendations, exclusive groups, bracket interaction, and FAQ.
+- **Documentation: See Also cross-links**: All 13 user guides end with a See Also section linking to related guides.
+- **Documentation: FAQ sections**: FAQ sections added to 5 guides (Bracket Compliance, Include/Exclude, Locks/Replace/Permalinks, Owned Cards, Budget Mode).
+- **Documentation: quality scoring and enforcement detail**: `theme_browser.md` documents the 4-factor badge scoring formula; `bracket_compliance.md` includes a full enforcement matrix.
+- **Consistent page headers**: All pages now share a unified header style — same font size, description line, and separator — replacing the previous mix of different heading sizes and layouts.
+- **"Help & Guides" button on home page**: Quick link to the documentation portal from the home page.
 
 ### Changed
-_No unreleased changes yet_
+- **Docker: `docs/` volume mount added**: `docker-compose.yml` and `dockerhub-docker-compose.yml` now mount `./docs` so documentation edits reflect immediately without a container rebuild.
 
 ### Fixed
 - **Bug: missing `idx` argument** in `project_detail()` call inside `theme_preview.py` caused theme preview pages to crash.

-- Bug fixes in `theme_preview.py` and `app.py` uncovered by the test suite.
-- Pydantic V2 deprecation warning resolved in `DeckExportRequest`.
+- **Bug: missing `idx` argument** in `project_detail()` call inside `theme_preview.py` caused theme preview pages to crash.
+- **Bug: `build_permalinks` router not mounted** in `app.py` caused all permalink-related endpoints to return 404.
+- **Pydantic V2 deprecation warning** silenced: `DeckExportRequest` now uses `model_config = ConfigDict(...)` instead of the deprecated inner `class Config`.
 
 ### Removed
-- 16 fragmented/stale test files consolidated or deleted; 7 permanently-skipped tests removed.
-
-## [4.4.2] - 2026-03-26
-### Added
-- **Community links**: GitHub, issue tracker, feature request, and DockerHub links in the footer and home page.
-- **Feature request templates**: GitHub issue templates for General Theme Requests, Commander-Specific Theme Requests, and Other Feature Requests.
-- **Feedback prompts**: Inline prompts on the Themes and Commanders pages linking to the relevant request templates.
-
-### Added
-- **Smart Land Bases checkbox**: The New Deck modal now has a **Smart Land Bases** checkbox in the Preferences section (checked by default). Enables or disables smart land analysis per-build without needing environment variables.
-
-### Removed
-- **`ENABLE_SMART_LANDS` environment variable**: Replaced by the per-build checkbox. Use `LAND_PROFILE` or `LAND_COUNT` for headless overrides.
-
-## [4.3.1] - 2026-03-25
-### Added
-- **Smart Land Bases**: Land count and basic-to-dual ratio are now adjusted automatically based on the commander's speed and color-pip intensity. Controlled by `ENABLE_SMART_LANDS=1` (default on in Docker).
-  - **Speed detection**: Commander CMC determines a speed category applied as an offset to the user's configured ideal land count. Fast (CMC < 3) = −2 lands, mid = ±0, slow (CMC > 4) = +2 to +4 scaling with color count.
-  - **Profile selection**: Basics-heavy (~60% basics) for 1–2 color / low-pip decks; Balanced for moderate pip density; Fixing-heavy (minimal basics, more duals/fetches) for 3+ color or high-pip pools (≥15 double-pip or ≥3 triple-or-more-pip cards).
-  - **ETB tapped tolerance** is automatically tightened for fast decks and loosened for slow decks.
-  - **Budget override**: Low-budget 3+ color decks are pushed to basics-heavy automatically.
-  - **Slot earmarking**: Non-land ideal counts are scaled to fit within the remaining slots after the land target is set.
-  - **Backfill**: A final land step pads with basics if any land phase falls short.
-  - Override with `LAND_PROFILE=basics|mid|fixing` or `LAND_COUNT=<n>`. A **Smart Lands** notice in the Land Summary explains the chosen profile.

+
+## FAQ
+
+**My deck passed Bracket 2 but the table says it feels more like Bracket 3 — why?**
+The compliance check runs against the official card lists (Game Changers, extra turns, tutors, combos). Cards not on those lists are not flagged even if they're powerful in context. Use the compliance report as a starting point, then discuss with your table.
+
+**I set `enforcement_mode: strict` but my Must Include card still violates the bracket.**
+Must Include cards always bypass enforcement filtering — they are inserted directly before pool selection runs. The compliance report will still flag the violation. Adjust the Must Include list or the bracket to resolve it.
+
+**Why does the compliance check flag a two-card combo I didn't intend?**
+Combo detection runs against a known list of two-card infinite combinations. If your synergies happen to match a known combo pattern, they'll be flagged. The report is informational — no cards are removed automatically.
+
+**Can I update the Game Changers list when WotC publishes new cards?**
+Yes. Edit the JSON files in `config/card_lists/` (e.g., `game_changers.json`). Each file has a `source_url` field pointing to the canonical source. Restart the server after editing.

 **Can I use budget mode with Must Include cards?**
 Yes. Must Include cards bypass the pool filter and are always added. They may appear as over-budget in the summary if they exceed the ceiling.
+
+**Why is the price shown different from what I see on a store site?**
+Prices are sourced from Scryfall bulk data and cached locally. They reflect a recent market median, not real-time retail or buylist prices. Check the stale indicator (clock icon) in the summary for cache age.
+
+**Can I set separate ceilings for different card types?**
+Not directly — the per-card ceiling applies to the full pool. To approximate type-specific limits, use Must Exclude to block expensive cards in a category before the build runs.

+# Build a Deck - Step-by-Step Guide
+
+Walk through the deck building wizard to create a Commander deck.
+
+---
+
+## Overview
+
+The deck builder guides you through a multi-step modal wizard that helps you configure and build a complete Commander deck. Each step lets you customize your deck's strategy, budget, and power level before generating the final list.
+
+Access the builder at `/build` or click **Build** in the sidebar.
+
+---
+
+## Step 1: Choose a Commander
+
+Select your commander from the search field in the modal. Type the commander's name to see matches.
+
+**Partner Commanders**: If your commander has Partner, Choose a Partner, or has a Background, you'll be prompted to select a second commander in a follow-up step.
+
+**Learn more**: [Partner Mechanics Guide](partner_mechanics.md)
+
+---
+
+## Step 2: Select Primary Themes
+
+Choose 1–3 core themes that define your deck's strategy by clicking theme chips in the modal. Themes are organized by pool size:
+
+- **Recommended**: Themes that work well with your commander (marked with ★)
+- **Pool Size Sections**: Themes grouped by available card count (Vast, Large, Moderate, Small, Tiny)
+
+Each theme displays a badge showing the approximate number of cards available for that theme in your commander's colors.
+
+**Tips**:
+- Start with 2–3 themes for focused strategies
+- Mix creature-tribal and mechanical themes for depth
+- Larger pool sizes give the builder more card options
+- Use AND mode for tighter synergy (cards match multiple themes)
+- Use OR mode for broader pools (cards match any theme)
+
+**Learn more**: [Theme Browser & Quality System](theme_browser.md)
+
+---
+
+## Step 3: Add Secondary/Synergy Themes (Optional)
+
+After selecting your primary themes, you can add additional themes using the "Additional Themes" textbox:
+
+- Enter theme names separated by commas
+- Add utility packages (e.g., card draw, removal)
+- Incorporate combo pieces or win conditions
+
+**Multi-Theme Fallback**: If you select multiple themes, the builder uses a fallback cascade to find cards that synergize across themes. If no exact matches exist, it expands to broader combinations.
+
+**Learn more**: [Random Build (Multi-Theme Cascade)](random_build.md#multi-theme-fallback-cascade)
+
+---
+
+## Step 4: Bracket Compliance
+
+Set power-level restrictions with bracket policies (required, defaults to Bracket 3):
+
+- **Bracket 1–4**: WOTC-defined power tiers
+- **Enforcement Modes**: Advisory, Strict, or Custom
+- **Banned Lists**: Automatically enforced per format rules
+
+Enable bracket enforcement with `ENABLE_BRACKETS=1` (default: on).
+
+**Learn more**: [Bracket Compliance Guide](bracket_compliance.md)
+
+---
+
+## Step 5: Preferences
+
+Configure optional build behaviors and card priorities:
+
+### Combo Preferences
+- **Prioritize combos**: Automatically include combo pieces near the end of the build
+  - **Combo count**: How many combos to include (default: 2)
+  - **Balance**: Early game, late game, or mix
+
+### Multi-Copy Package
+- **Enable Multi-Copy package**: Include multiple copies of cards for token/tribal strategies
+  - Works with archetypes like Rat Colony, Relentless Rats, Dragon's Approach
+  - Automatically suggests Thrumming Stone synergy when applicable
+  - **Learn more**: [Multi-Copy Package](multi_copy.md)
+
+### Owned Card Preferences
+- **Use only owned cards**: Limit the pool to cards you already own
+- **Prefer owned cards**: Still allow unowned cards, but rank owned cards higher
+
+Upload your collection at `/owned` or before starting a build.
+
+**Learn more**: [Owned Cards Guide](owned_cards.md)
+
+### Land Base Options
+- **Swap basics for MDFC lands**: Modal DFC lands replace matching basic lands automatically
+- **Smart Land Bases**: Auto-adjust land count and mana curve based on commander speed and color complexity
+
+**Learn more**: [Land Bases Guide](land_bases.md)
+
+---
+
+## Step 6: Ideal Counts
+
+Set target counts for key card categories using sliders or number inputs:
+
+- **Ramp**: 0–30 cards (default varies by commander)
+- **Lands**: 25–45 cards (default varies by commander speed)
+- **Basic Lands**: 0–40 cards (subset of total lands)
+- **Creatures**: 0–70 cards
+- **Removal**: 0–30 cards (spot removal)
+- **Wipes**: 0–15 cards (board wipes)
+- **Card Advantage**: 0–30 cards (draw/recursion)
+- **Protection**: 0–20 cards (counterspells, indestructible effects)
+
+**Warning**: The builder validates your totals. If ideal counts exceed 99 cards, reduce totals to avoid build issues.
+
+**Tips**:
+- Start with default recommendations
+- Adjust based on your deck's strategy
+- Category totals may overlap (e.g., a creature that ramps counts in both)
+
+---
+
+## Step 7: Include/Exclude Specific Cards (Optional)
+
+Fine-tune your deck with must-have or must-avoid lists:
+
+- **Include List**: Guarantee specific cards in the deck (max 10)
+- **Exclude List**: Prevent certain cards from being chosen (max 15)
+- **File Upload**: Upload .txt files with one card name per line
+- **Fuzzy Matching**: Card names are validated with approximate matching
+
+Enable with `ALLOW_MUST_HAVES=true`.
+
+**Learn more**: [Include/Exclude Cards Guide](include_exclude.md)
+
+---
+
+## Step 8: Budget Constraints (Optional)
+
+Control deck cost with budget limits:
+
+- **Total Budget ($)**: Set a deck cost ceiling — cards over budget will be flagged
+- **Per-Card Ceiling ($)**: Flag individual cards above this price
+- **Pool Filter Tolerance (%)**: Cards exceeding the per-card ceiling by more than this % are excluded from the card pool (default: 15%)
+  - Set to 0 to hard-cap at the ceiling exactly
+
+Budget filtering uses cached Scryfall prices and respects owned card preferences.
+
+Enable with `ENABLE_BUDGET_MODE=1`.
+
+**Learn more**: [Budget Mode Guide](budget_mode.md)
+
+---
+
+## Step 9: Advanced Build Options
+
+### Quick Build / Skip Controls
+Skip building specific card types to speed up the process:
+- Skip lands (use with external manabase tools)
+- Skip ramp/removal/draw
+- Customize card type distribution
+
+**Learn more**: [Quick Build & Skip Controls](quick_build_skip_controls.md)
+
+### Batch Build Mode
+Generate multiple deck variations at once:
+- Build 1–10 decks with the same configuration
+- Compare results to see variance in card selection
+
+Enable with `ENABLE_BATCH_BUILD=1`.
+
+**Learn more**: [Batch Build & Compare](batch_build_compare.md)
+
+---
+
+## Step 10: Build & Review
+
+Once configured, click **Build Deck** to generate your decklist. The builder will:
+
+1. Select cards based on your themes and synergies
+2. Apply budget and bracket constraints
+3. Optimize the manabase for your color identity
+4. Balance card types (creatures, spells, lands)
+
+### After Building
+
+The results page shows:
+
+- **Full Decklist**: All 100 cards with images and prices
+- **Summary Stats**: Mana curve, color distribution, card types
+- **Export Options**: CSV, TXT, JSON, or Arena format
+- **Deck Actions**: Lock cards, replace specific cards, rebuild with changes
+
+**Lock & Replace**: Found a card you want to keep? Lock it, then replace others without losing your favorites.
+
+**Learn more**: [Locks, Replace & Permalinks](locks_replace_permalinks.md)
+
+---
+
+## Alternative Build Modes
+
+### Random Build Mode
+Let the builder choose themes, budget, and configuration automatically with seeded randomization.
+
+**Learn more**: [Random Build Guide](random_build.md)
+
+### Batch Build & Compare
+Generate multiple deck variations at once and compare strategies side-by-side.
+
+**Learn more**: [Batch Build & Compare](batch_build_compare.md)
+
+---
+
+## Tips for Success
+
+1. **Start Simple**: Choose 2–3 strong themes for your first build
+2. **Check Quality Badges**: Higher quality themes have better curation
+3. **Review Theme Pool Sizes**: Larger pools give the builder more options
+4. **Use Permalinks**: Save your deck configurations for tweaking later
+5. **Iterate**: Lock good cards and rebuild to refine your strategy
+
+---
+

+## FAQ
+
+**Can I include a card that isn't in my commander's color identity?**
+The builder will attempt to add it but will silently skip it if the card is outside the commander's color identity. Check the build summary for skipped cards.
+
+**What happens if my Must Include list makes the deck exceed 100 cards?**
+Must Include cards are inserted before pool selection fills the remaining slots. The total is always capped at 100 cards, with Must Includes taking priority over pool-selected cards.
+
+**Do Must Include cards count against bracket compliance?**
+Yes. A Must Include card that violates your bracket (e.g., a Game Changer at Bracket 2) will be flagged in the compliance report. The card stays in the deck regardless of enforcement mode.

+
+## FAQ
+
+**Can I share a permalink with someone who has a different card catalog version?**
+Permalinks encode names and settings, not card data. As long as the commander and theme names are still valid in the recipient's catalog, the build will restore correctly. Cards that no longer exist in the catalog will be skipped.
+
+**Are locks preserved when I export to CSV or TXT?**

+
+**What if I accidentally replace a card I wanted to keep?**
+Replaced cards move out of the deck immediately. If you haven't rebuilt, you can replace again to bring a similar card back in. For guaranteed cards, use Must Include so they aren't displaced by Replace or Rebuild.

+# Multi-Copy Package
+
+Build decks that run many copies of a single card-type — Relentless Rats, Shadowborn Apostles, and more.
+
+---
+
+## Overview
+
+Some Magic cards have a printed exception allowing any number of copies in a Commander deck. The Multi-Copy Package feature lets you include a chosen archetype card at a configured count and builds the rest of the deck around it.
+
+Enable with `ALLOW_MUST_HAVES=1` (default: on). The **Enable Multi-Copy package** checkbox appears in the New Deck modal preferences section.
+
+---
+
+## How It Works
+
+1. Check **Enable Multi-Copy package** in the New Deck modal.
+2. When you add an eligible card to Must Include, a **count picker dialog** appears. Set the number of copies.
+3. The builder reserves those slots for the archetype card before filling the rest of the deck from the theme pool.
+4. The multi-copy card is locked automatically and appears in Step 5 alongside the rest of the build.
+
+The builder auto-suggests the dialog when your commander's theme tags match the archetype's trigger conditions. You can also manually add any eligible card via the quick-add input and set a count freely.
+
+---

+Cards with a **printed cap** (Nazgûl: 9, Seven Dwarves: 7) cannot exceed their cap — the count picker enforces the maximum.

+
+## Exclusive Groups
+
+Rat Colony and Relentless Rats are mutually exclusive — they share the `rats` exclusive group. If both are added, a dialog will prompt you to choose one. Only one rat archetype can be active per build.
+
+---
+
+## Count Recommendations
+
+For uncapped archetypes, the suggested range is **20–30 copies**. This leaves room for a commander, support spells, and lands in a 100-card deck. The sweet spot is often 20–25 copies, which allows ~15–20 support cards and ~35 lands.
+
+Archetypes with many synergy triggers (Shadowborn Apostle, Relentless Rats) can push toward 30 when the commander specifically supports the archetype.
+
+---
+
+## Bracket Interaction
+
+High copy counts of powerful archetypes can affect bracket compliance:
+
+- **Thrumming Stone** (which many of these archetypes synergise with) is a Game Changer — using it in Bracket 2 or below will trigger a compliance warning.
+- The archetype cards themselves are generally not on the Game Changers list, but check the compliance report in Step 5 after building.
+
+---
+
+## Headless / CLI
+
+Set the multi-copy card and count in your JSON config via the `must_include` list. The count picker is a UI affordance — in headless mode, add the card name the desired number of times:
+
+```json
+{
+  "must_include": [
+    "Relentless Rats", "Relentless Rats", "Relentless Rats",
+    "Relentless Rats", "Relentless Rats"
+  ]
+}
+```
+
+---
+
+## FAQ
+
+**Why doesn't the count picker appear when I add a multi-copy card?**
+The auto-suggest only triggers when your commander's theme tags match the archetype's trigger conditions. If you don't see the dialog, try adding the card manually via the quick-add input — the dialog will appear for recognized archetype names regardless of commander.
+
+**Can I run a multi-copy package with `owned_only` mode?**
+Yes, but you need that many copies of the card in your owned card library. The builder will include the configured count regardless of owned status for Must Include cards — they bypass the owned filter.
+
+**Will the multi-copy card count toward my ideal creature or spell count?**
+Yes. Multi-copy creature archetypes (e.g., Relentless Rats) count toward the creature ideal, and non-creature archetypes (e.g., Dragon's Approach) count toward the spell ideal. Adjust your ideal counts in Step 6 accordingly.

+
+## FAQ
+
+**My owned card file uploaded but no cards are being filtered — what's wrong?**
+Check that the file is in a supported format (plain text, one card per line, or a standard CSV export). Card names must match the Scryfall canonical name exactly (e.g., "Sol Ring" not "sol ring"). Check the diagnostics page for parse errors.
+
+**Can I use multiple owned card files?**
+Yes. All files in the `owned_cards/` directory are merged automatically. If the same card appears in multiple files, it is counted once.
+
+**Does `prefer_owned` guarantee my owned cards appear in the deck?**
+No — `prefer_owned` adds a weight boost during pool selection, but owned cards compete with the rest of the pool. If you need a specific card guaranteed, add it to Must Include instead.
+
+**What happens if I'm in `owned_only` mode and there aren't enough owned cards in a category?**
+The builder fills the category with the cards available and may produce a deck with fewer cards than the ideal count for that slot. The build summary will note any under-filled categories.

+## Multi-Theme Fallback Cascade
+
+When you specify multiple themes (Primary + Secondary + Tertiary), the builder attempts to find commanders matching all themes using a **fallback cascade**. This ensures you get a valid commander even when exact combinations don't exist:
+
+**Fallback Order** (AND logic):
+1. **Primary + Secondary + Tertiary** — Exact match (all 3 themes)
+2. **Primary + Secondary** — Drop tertiary theme
+3. **Primary + Tertiary** — Drop secondary theme (treat tertiary as secondary)
+4. **Primary only** — Use only the primary theme
+5. **Synergy fallback** — Find commanders with theme tag overlap/token substring matches with Primary
+6. **Full pool fallback** — Any commander (last resort)
+
+**Fallback Notices:**
+- **Combo Fallback** (blue/info): One or more themes were dropped (combinations 2-4). The builder found a commander but couldn't match all requested themes.
+- **Synergy Fallback** (amber/warning): Exact theme match failed; using commanders with overlapping keywords/tokens from your primary theme.
+- **Full Pool Fallback** (strong warning): No theme matches found; falling back to the entire commander pool. Your theme inputs were too restrictive.
+
+**Example:**
+- Request: `Primary: Aggro`, `Secondary: Tokens`, `Tertiary: Goblins`
+- If no commander has all three tags, the builder tries `Aggro + Tokens`, then `Aggro + Goblins`, then `Aggro` only
+- Fallback reason is displayed clearly in the result, explaining which combination was used
