 - Owned cards workflow: Prompt after commander to "Use only owned cards?"; supports `.txt`/`.csv` lists in `owned_cards/`. Owned-only builds filter the pool; if the deck can't reach 100, it remains incomplete and notes it. When not owned-only, owned cards are marked with an `Owned` column in the final CSV.
 - Exports: CSV/TXT always; JSON run-config exported for interactive runs and optionally in headless (`HEADLESS_EXPORT_JSON=1`).
 - Data freshness: Auto-refreshes `cards.csv` if missing or older than 7 days and re-tags when needed using `.tagging_complete.json`.
+- Web setup speed: initial tagging runs in parallel by default for the Web UI. Configure with `WEB_TAG_PARALLEL=1|0` and `WEB_TAG_WORKERS=<N>` (compose default: 4). Falls back to sequential if parallel init fails.
+ - Visual summaries: Mana Curve, Color Pips and Sources charts with hover-to-highlight and copyable tooltips. Sources now include non-land producers and colorless 'C' (toggle display in UI). Basic lands reliably counted; fetch lands no longer miscounted as sources.
+ - Favicon support: app branding icon served at `/favicon.ico` (ICO/PNG fallback).
+ - Prefer-owned option in the Web UI Review step prioritizes owned cards while allowing unowned fallback; applied across creatures and spells with stable reordering and gentle weight boosts.
+ - Owned page: 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. Upload-time enrichment and de-duplication speeds up page loads.
+ - Staged build visibility: optional "Show skipped stages" reveals phases that added no cards with a clear annotation.
 
 ## What’s new
 - Web UI: Staged run with a new "Creatures: All-Theme" phase in AND mode; shows matched selected themes per card for explainability. Step 2 UI clarifies AND/OR with a tooltip and restyled Why panel.
 - Builder: AND-mode pre-pass for creatures; spells updated to prefer multi-tag overlap in AND mode.
+ - Reporting: deck summary includes per-color card lists for Pips and Sources; colorless 'C' surfaced and totals corrected.
+ - UI Polish: list-mode highlight wraps only the card name. Chart tooltips include a Copy action with hover persistence.
+ - Exports: CSV gains fallback oracle text for basic lands (Plains/Island/Swamp/Mountain/Forest/Wastes) when missing.
 - Config: `tag_mode` added to JSON and accepted from env (`DECK_TAG_MODE`).
+ - Prefer-owned bias across creatures and spells selections; Review step includes a toggle next to the owned-only control.
+ - Owned page features and performance improvements via upload-time enrichment and persistence.
+ - Staged build UI can surface skipped stages when enabled.

 - Headless: `tag_mode` supported from JSON/env and exported in interactive run-config JSON.
 - Docs: README, DOCKER, and Windows Docker guide updated; PowerShell-friendly examples.
 - Docker: compose `web` service added; volumes clarified.
+ - Visual summaries and diagnostics: added `/healthz` endpoint with version/uptime and request-id propagation on all responses.
+ - Review step consolidates owned-only and prefer-owned controls; Step 5 is status-only with an "Edit in Review" link for changes.
+ - Owned lists processing moved to upload-time in Web; per-request parsing removed. Enriched store powers fast Owned page and deck-building.
+ - Finished Decks page uses a dropdown theme filter with shareable state.
 
 ### Tagging updates
 - Explore/Map: treat "+1/+1 counter" as a literal; Explore adds Card Selection and may add +1/+1 Counters; Map adds Card Selection and Tokens Matter.
