Web UI polish: thumbnail-hover preview, white thumbnail selection, Themes bullet list; global Scryfall image retry (thumbs+previews) with fallbacks and cache-bust; standardized data-card-name. Deck Summary alignment overhaul (count//name/owned grid, tabular numerals, inset highlight, tooltips, starts under header). Added diagnostics (health + logs pages, error pages, request-id propagation), global HTMX error toasts, and docs updates. Update DOCKER guide and add run-web scripts. Update CHANGELOG and release notes template.
