feat: align builder commander hover with deck view

- reuse shared hover metadata in Step 5 and keep the preview in-app\n- let hover reasons expand without an embedded scrollbar\n- document the hover polish in CHANGELOG and release notes

CHANGELOG.md

@@ -18,11 +18,25 @@ This format follows Keep a Changelog principles and aims for Semantic Versioning
 - Included the tiny `csv_files/testdata` fixture set so CI fast determinism tests have consistent sample data.
 
 ### Changed
+- Owned Cards library tiles now use larger thumbnails and wider columns, and virtualization only activates when more than 800 cards are present to keep scrolling smooth.
 - Theme catalog schema now accepts optional `id` values on entries so refreshed catalogs validate cleanly.
 - CI installs `httpx` with the rest of the web stack and runs pytest via `python -m pytest` so FastAPI tests resolve the local `code` package correctly.
 - Relaxed fast-path catalog validation to allow empty synergy lists while still warning on missing or malformed data types.
+- Deck summary list view now includes inline flip controls for double-faced cards, keeping text mode feature parity with thumbnail mode.
+- Hover panel theme chips now highlight only the themes that triggered a card’s inclusion while the full theme list displays as a muted footer without legacy bracket formatting.
+- Finished deck summaries now surface overlap chips using sanitized saved metadata with a themed fallback so exported decks match the live builder UI, and hover overlap pills adopt larger, higher-contrast styling on desktop and mobile.
+- Builder card tiles now reserve the card art tap/click for previewing; locking is handled exclusively by the dedicated 🔒 button so mobile users can open the hover panel without accidentally changing locks.
+- Builder hover tags now surface normalized theme labels (e.g., “Card Advantage”) and suppress internal `creature_add • tag:` prefixes so build-stage pills match the final deck experience.
+- Builder Step 5 commander preview now reuses the in-app hover panel (removing the external Scryfall link) and the hover reasons list auto-expands without an embedded scrollbar for easier reading on desktop and mobile.
+- Finished deck commander preview now mirrors builder hover behavior with deck-selected overlap chips, the full commander theme list, and suppresses the external Scryfall link so tapping the thumbnail consistently opens the in-app panel across desktop and mobile.
 
 ### Fixed
+- Hover card role badge is hidden when no role metadata is available, eliminating the empty pill shown in owned library popovers.
+- Random Mode fallback warning no longer displays when all theme inputs are blank.
+- Reinstated flip controls for double-faced cards in the hover preview and ensured the overlay button stays in sync with card faces.
+- Hover card panel adapts for tap-to-open mobile use with centered positioning, readable scaling, and an explicit close control.
+- Mobile hover layout now stacks theme chips beneath the artwork for better readability and cleans up theme formatting.
+- Duplicate overlap highlighting on desktop hover has been removed; theme pills now render once without stray bullets even when multiple overlaps are present.
 - Headless runner no longer loops on the power bracket prompt when owned card files exist; scripted responses now auto-select defaults with optional `HEADLESS_USE_OWNED_ONLY` / `HEADLESS_OWNED_SELECTION` overrides for automation flows.
 - Regenerated `logs/perf/theme_preview_warm_baseline.json` to repair preview performance CI regressions caused by a malformed baseline file and verified the regression gate passes with the refreshed data.

 - CI updates install the missing `httpx` dependency and run pytest through `python -m` to ensure the web stack tests import the local package correctly.
 - Fast-path catalog validation now tolerates empty synergy lists while still flagging missing fields or non-string entries.
 - Committed deterministic CSV fixtures under `csv_files/testdata` so CI random-mode checks have a stable dataset.
+- Owned Cards library tiles are larger, virtualization only kicks in for very large libraries, and popovers no longer show empty role pills.
+- Random Mode fallback warning remains hidden when no theme filters are provided, keeping Surprise Me runs noise-free.
+- Hover previews regained the double-faced card flip button with state synced to the main tile, highlight only the themes that triggered inclusion, and present a mobile-friendly tap layout with centered positioning plus a close control.
+- Deck summary text view exposes inline flip toggles for double-faced cards so counts and face switching stay in sync.
+- Finished deck summaries now reuse sanitized metadata (with a fallback to deck meta) to display overlap chips that mirror the builder view, and hover overlap pills feature larger, higher-contrast styling for readability.
+- Builder Step 5 commander preview now leverages the in-app hover panel (dropping the external Scryfall link) and the hover reasons list expands naturally without a cramped scrollbar.
+- Finished deck commander preview now mirrors the builder hover chips, showing deck-selected theme overlaps alongside the full commander theme list while keeping thumbnail taps inside the app instead of bouncing to Scryfall.
 - Delivered multi-theme random builds with deterministic cascade, strict match support, and polished HTMX/UI flows.
 - Added opt-in telemetry counters, reroll throttling safeguards, and structured diagnostics exports.
 - Expanded tooling, documentation, and QA coverage for theme governance, performance profiling, and seed history management.

 - Reroll throttle enforcement with banner/countdown messaging plus override hooks for attempts and timeout controls.
 - Expanded fast tests validating telemetry counters, throttle behavior, and reroll permutations.
 
+### UI polish
+- Owned Cards library grid uses 160px thumbnails, wider columns, and defers virtualization until large collections to ensure smooth scrolling.
+- Hover card popovers hide the role badge when a card has no role metadata, preventing blank pills in owned library previews.
+- Hover card previews now include a flip control for double-faced cards, stay synchronized with the tile button, highlight the active inclusion themes, and present a centered, readable mobile layout when tapped.
+- Finished deck exports render the same overlap chips as the live builder, backed by metadata fallback logic, and the hover overlap pills are larger with improved contrast.
+- Finished deck commander popovers reuse deck metadata to display overlap chips and commander theme lists, and the commander thumbnail no longer opens Scryfall so tap-to-preview is consistent on mobile.
+- Builder stage card tiles now keep the card art tap/click dedicated to previewing while the lock state is controlled solely by the 🔒 button, preventing accidental locks on touch devices.
+- Builder hover previews now use normalized theme labels (e.g., “Card Advantage”), suppress internal prefixes so build-mode pills match the finished deck summary, and the Step 5 commander preview stays in-app with hover reasons expanding without scrollbars.
+- Deck summary text rows gained inline flip buttons beside card counts to mirror thumbnail behavior for double-faced cards.
+- Random Mode fallback banner is suppressed when all theme inputs are empty so Surprise Me runs stay uncluttered.
+
 ### Tooling & docs
 - Random theme exclusion catalog with reporting script and documentation, alongside a multi-theme performance profiler and regression guard.
 - Taxonomy snapshot tooling, splash penalty analytics, and governance documentation updated for strict alias and example enforcement.
