## v3.0 Design System & Visual Polish (Shipped: 2026-05-17)
**Delivered:** Full design system ported from go-backend and applied to every product surface — auth pages, app shell, tablo list, tablo detail, chat, and planning.
**Phases completed:** 13-17 (5 phases, 16 plans)
**Key accomplishments:**
- Built a complete CSS token vocabulary and typed templ component library (11 types: button, badge, card, modal, empty-state, table, icon-button, input, textarea, select, form-field) with a build-tag-gated `/ui-catalog` visual verification page.
- Restyled auth pages (login/signup) with gradient animated background, centered auth-card, brand logo, and Google Material Design sign-in button with Roboto font.
- Implemented app shell: sidebar with brand section, icon nav items, tablo list section, and user footer; tablo list with project-card grid, color avatars, and action controls.
- Restyled tablo detail: project-card-top header, tasks-section kanban, etapes section, and files table using `@ui.Table` with `@ui.EmptyState` fallback.
- Added own-vs-others chat bubbles with brand-tint right-alignment and planning day-separator event list using overview-section layout.
**Stats:**
- 150 files changed, +23,505 / −993 lines across v3.0 git range
- 5 phases, 16 plans
- 2 days (2026-05-16 → 2026-05-17)
- Go backend: ~18,600 non-test LOC + ~3,400 templ LOC
**Git range:** `3b9bd62` → `fa48d81`
**Known deferred items at close:** 6 acknowledged open artifact items (all pre-existing from v1.0/v2.0). See `.planning/STATE.md` Deferred Items.
