- Reward is now streak-multiplied: units per day = streakOnDay(d) × triangular(checks);
recalibrate pixelsPerCheck (÷ triangular(30)) and the upload finish-day estimate.
- Rename the "Backup" settings tab to "Data" and add a double-confirm "Wipe all data" action.
- Add a page footer disclosing authorship (Claude Code — Sonnet 5, Opus 4.8 & Fable 5).
- About page now explains exactly how pixels are earned (per-check escalation + streak multiplier).
- Allow uploading an image during first-run onboarding, not just presets.
- Update DESIGN.md, ARCHITECTURE.md, README.md to match.
