Closes #4282. mara: "scope looks good" — approving the plan posted there (manifest + icons + minimal shell-only service worker + iOS meta tags) and both explicit questions (network-first-with-offline-fallback, never cache /api/*). docs/web-ui/design-guide.md's "Layout & viewport" section already asserted swarm-ui is installable as a PWA — this is what actually backs it. - manifest.webmanifest: name/icons/start_url/standalone display, theme #cba6f7 / background #1e1e2e matching the mocha --purple/--bg values. - sw.js: plain JS, not TypeScript — the DOM lib swarm-ui's own tsconfig uses and the WebWorker lib a service worker's globals need are mutually exclusive in one tsc program, not worth a second tsconfig for a self-contained ~100-line file. Scoped to the app shell only, never touches /api/* at all, network-first with offline-fallback-to-cache (not cache-first) since main.js/main.css are unhashed filenames and a cache-first SW would risk wedging an operator on stale JS after a deploy. - index.html: manifest link, theme-color meta, iOS apple-mobile-web-app-* tags (Safari ignores the manifest spec). - main.tsx: feature-detected SW registration. - branding/hyperhive-maskable.svg: hyperhive.svg's own artwork already fills nearly its whole canvas, so a maskable icon needs a padded variant or an OS mask crops the outer ring/corner brackets — embeds the original via a scaled <image> ref rather than duplicating markup. - nix/packages/swarm-ui.nix: rasterizes icon-192/512/512-maskable.png from the branding SVGs at build time via librsvg, rather than checking in static PNGs. Verified for real: typecheck+build green, and a real headless-chromium tab driven over CDP confirms the service worker registers and becomes the active controller, and a simulated-offline reload still serves the full cached shell rather than a browser error page. nix build .#swarm-ui also verified green, including the rasterized icon output.
