Scaffold an Expo + TypeScript app for Dokio, the app that scans Behördenpost and explains it in plain language, and build the four screens specified in "Dokio Design.dc.html": 4a Onboarding, full-bleed dither gradient 4b Home, dithered scan card 3a Kamera, mocked viewfinder 3b Archiv, search + filters + month groups Design tokens from the turn 4 blue palette live in src/theme.ts. Content is mocked in src/data/letters.ts, taken verbatim from the doc. DitherBackground is a GLSL port of the doc's dither-bg.js, which drew a low-resolution canvas and upscaled it with image-rendering: pixelated; the fragment shader snaps to the same grid instead. Two notes on the port: - The original's fract(sin(x) * 43758.5453) hash only distributes well in float64. A fragment shader's highp float has ~24 mantissa bits, so it collapsed to a near-constant field and the gradient bands rendered straight rather than warped. Replaced with Hoskins' hash, verified against the original running side by side. - The 4x4 Bayer matrix is built recursively rather than as a lookup, which avoids dynamic array indexing; the construction reproduces all 16 entries of the original exactly. The camera screen deliberately stops short of expo-camera: the viewfinder is a static stand-in, so the flow is navigable without permissions. The 2a result screen is not part of turns 3 and 4 and is not included. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
