Add a Style setting beside mode, accent, radius and background. Nostalgia restyles the app through
tokens only (neutral surface palettes, system type, flat shell, top glow) and pins background,
opacity and brightness. Add a top glow reach slider for both styles. Tidy the theme layer first:
charts read live tokens, bare `rounded` follows the radius scale, one shared sign-in toolbar.
Also carries the settings page header redesign.
Add vite-plugin-pwa with Workbox in generateSW mode. Includes a web app
manifest (standalone display, shortcuts for Dashboard/Libraries/Settings),
iOS meta tags, and a service worker that pre-caches the app shell and uses
CacheFirst for book cover and thumbnail endpoints (max 200 entries, 30-day TTL).
Add useInstallPrompt composable that captures the beforeinstallprompt event
and exposes isInstallable/installApp. Wire an install button into SidebarFooter
that appears only when the browser signals the app is installable.
Generate PWA icons (64, 192, 512, maskable-512, apple-touch-icon-180) from a
new pwa-icon-source.svg using @vite-pwa/assets-generator with minimal2023Preset.
Add dev-dist to .gitignore to exclude the dev-mode SW output.
