- Multi-copy archetypes (Web): opt-in modal suggests packages like Persistent Petitioners, Dragon's Approach, and Shadowborn Apostle when viable; choose quantity and optionally add Thrumming Stone. Applied as the first stage with ideal count adjustments and a per-stage 100-card safety clamp. UI surfaces adjustments and a clamp chip.
### Changed
- Multi-copy modal now appears immediately after commander selection (pre-build) in Step 2. This reduces surprise and lets users make a choice earlier.
- Stage order updated so the Multi-Copy package is applied first in Step 5, with land steps following on the next Continue. Lands now account for the package additions when filling.
### Fixed
- Ensured apostrophes in multi-copy card names remain safe in templates while rendering correctly in the UI.
- Web UI performance: optional virtualized grids/lists in Step 5 and Owned (enable with `WEB_VIRTUALIZE=1`).
- Virtualization diagnostics overlay (when `SHOW_DIAGNOSTICS=1`); press `v` to toggle per‑grid overlays and a global summary bubble with visible range, totals, render time, and counters.
- Image polish: lazy‑loading with responsive `srcset/sizes` and LQIP blur/fade‑in for Step 5 and Owned thumbnails and the commander preview image.
- Short‑TTL fragment caching for template partials (e.g., finished deck summaries and config run summaries) to reduce re‑render cost.
- Prefer-owned option in Review: bias selection toward owned cards while allowing unowned fallback (stable reorder + gentle weight boosts applied across creatures and spells)
- Owned page enhancements: export TXT/CSV, sort controls, live "N shown," color identity dots, exact color-identity combo filters (incl. 4-color), viewport-filling list, and scrollbar styling
- Finished Decks: theme filters converted to a dropdown with shareable state
- Staged build: optional "Show skipped stages" toggle to surface stages that added no cards with a clear annotation
- Owned/Not-owned badges visible across views; consolidated CSS for consistent placement
- Visual summaries: Mana Curve, Color Pips and Sources charts with cross-highlighting to cards; tooltips show per-color card lists and include a Copy action
- Source detection: include non-land mana producers and colorless 'C'; basic lands reliably counted; fetch lands excluded as sources
- Favicon support: `/favicon.ico` served (ICO with PNG fallback)
- Theme UX: Header includes a Reset Theme control to clear browser preference and reapply server default (THEME) or system mapping. Diagnostics page shows resolved theme and stored preference with a reset action.
- 404s from Starlette now render the HTML 404 page when requested from a browser (Accept: text/html)
- Owned page UX: full-size preview now pops on thumbnail hover (not the name); selection highlight tightened to the thumbnail only and changed to white for better contrast; Themes in the hover popout render as a larger bullet list with a brighter "THEMES" label
- Image robustness: standardized `data-card-name` on all Scryfall images and centralized retry logic (thumbnails + previews) with version fallbacks (small/normal/large) and a single cache-bust refresh on final failure; removed the previous hover-image cache to reduce complexity and overhead
- Layout polish: fixed sidebar remains full-height under the banner with a subtle right-edge shadow for depth; grid updated to prevent content squish; extra scroll removed; footer pinned when content is short.
- Deck Summary list view: rows use fixed tracks for count, ×, name, and owned columns (monospace tabular numerals) to ensure perfect alignment; highlight is an inset box-shadow on the name to avoid layout shifts; long names ellipsize with a tooltip; list starts directly under the type header and remains stable on full-screen widths
- Deck summary alignment issues in some sections (e.g., Enchantments) fixed by splitting the count and the × into separate columns and pinning the owned flag to a fixed width; prevents drift across responsive breakpoints
- Banned list filtering applied consistently to all color/guild CSV generation paths with exact, case-insensitive matching on name/faceName (e.g., Hullbreacher, Dockside Extortionist, and Lutri are excluded)
