Board-v3 (TSK-0099, codex, architect-reviewed 7/7):
- kanban columns fill viewport height, scroll inside the column (no page scroll)
- padding/margin between task cards
- bar-chart HTML-escape bug fixed (est marker inserted raw, not esc())
- half-donut center text centered
- task detail opens in a modal (title/description/activity, empty sections hidden)
instead of navigating to /tasks
- header-jitter on page switch fixed via scrollbar-gutter: stable
- SSE connection-leak/freeze fixed (EventSource closed on pagehide/beforeunload)
Animated KPI icons (architect):
- vendored lottie-web player + Lottie card icons under assets/, served via a
path-traversal-guarded /card-assets/* route (offline-safe, no CDN)
- state-driven: loop-while-active (open/in_progress/review), pulse-on-change
(active/done/agents); light KPI card bg so the black-line icons read clearly
