- add Claude/OpenAI/Cursor/Grok brand SVGs under app/renderer/assets/providers
- ProviderLogo component: brand-orange Claude in both themes; light/dark
monochrome variants for OpenAI/Cursor/Grok swapped per active theme
- show the logo in the provider dropdown (trigger + menu items) and in
Settings > Providers, left of each provider name
typecheck clean; 128/128 tests pass.
- Period seg now uses the 5 real CLI periods (Today/7D/30D/Month/6M);
6M maps to 'all' (matches the menubar).
- Provider control is a real dropdown listing only DETECTED providers
(accumulated from current.providers so it never shrinks) + All.
- New RangeCalendar: month grid with click-and-drag range selection
(+ two-click fallback, future-date disabling) behind a calendar button;
commits a custom {from,to} threaded to Overview/Spend/Models/Optimize
via new --from/--to CLI args (Plans/Settings stay period-only).
- typecheck clean, 87 vitest pass.
Ports the wireframe window shell into React with exact markup/classes:
- Shared components: Window, Sidebar (traffic lights, gradient mark, six
nav items with ⌘ keycaps + active `on` rail, status line), TopBar
(title, scope, period SegTabs Today/7D/30D/Month/6M/Custom, ProviderPop),
Panel, Stat, SegTabs, ProviderPop, Hint.
- usePolled(fetcher, deps): generic 30s poll + loading/error state,
errors normalized to CliError.
- App.tsx: local section state switches the content outlet; the Overview
placeholder round-trips getOverview('30days','all') and renders the raw
current.cost, with an honest first-run "locate CLI" state when the
codeburn binary isn't found (never a crash).
- Sidebar.test.tsx: six nav items, click routes onNavigate, active `on`.
