Brand: new "atlas plate" mark (grid plate, A-as-graph constellation, timeline "now" node) shared by logo.svg,
lockups, favicon (simplified grid), apple/PWA icons, root OG wallpaper with live counters; theme-inverting
--brand-* tokens. Shell: header nav Models · Frontier · Benchmarks · Prices · Research · Graph · Changes · More ▾
(keyboard menu), mobile tab bar with grouped More sheet, footer with credits line, About page rewritten.
Command palette: commands with fuzzy match, recents, type prefixes (m: b: o: p: h:), ">" mode, theme/density
actions. Evidence drawer (right panel / bottom sheet) fed by /provenance → /history → inline fallback, wired
into KeyValue (slug prop) and ProvenanceInline; SpecTable/Capabilities pass slug. Density toggle
(comfortable | compact | dense) via CSS variables; pre-paint scripts moved to lib/prepaint.ts (server-safe —
client-module string exports reached the server as stubs). Charts: InteractiveLineChart, StepChart,
Sparkline trend, ScatterChart, Heatmap, TimelineLanes, lineLayout. Terminal primitives: TerminalLayout,
FilterSheet, DataStrip, Ticker, SectionNav; Sheet + Hint UI. Local watchlist + WatchButton + /watchlist.
Homepage 3.0: compact hero, live strip with definitions, ticker, editorial grid (today, frontier moves,
leaders, price moves, open weights, research), release timeline lanes, graph teaser, signature products.
QA: screens.mjs shell sweep 320–1920 + touch targets, SHELL_ONLY mode; shell.mjs flows. docs/FRONTEND.md §2 §4 §9.
