Two things this session depended on lived only in a scratchpad, so the next agent would have had to reinvent them from a prose hint: - scripts/screenshot-fonts.conf, now applied by screenshot.ts itself. Without it this container renders every generic font family as Fira Code and the UI looks monospaced in a way no user sees — a trap that nearly produced a "fix" for a font bug that does not exist. - scripts/demo-data.ts, which seeds a visibly synthetic dataset. Without it every screenshot shows an app full of zeros, because Chrome starts from a fresh profile each run. CLAUDE.md now carries the two-command recipe verbatim instead of "point FONTCONFIG_FILE at an override", and says why --reload is mandatory. Verified from a clean shell with no environment set. Also flags docs/superpowers/plans/2026-09-01-budget-app.md as a historical record: its snippets still show CURRENCIES and CURRENCY_DIGITS, which no longer exist, and an agent reading it as current would be misled.

Budget 2.0
A personal budgeting PWA. Envelope-style monthly budgets with rollover, split purchases, finance plans, multi-currency, and JSON/ODS export. All data lives in your browser — there is no server and no account.
Development
bun install
bun --hot src/index.ts # dev server with hot reload
bun test # run the test suite
bun run build # production build into dist/
Self-hosting with Docker
docker build -t budget2 .
docker run --rm -p 3000:3000 budget2
To serve from a subpath, build and run with BUN_PUBLIC_BASE_PATH:
docker build -t budget2 --build-arg BUN_PUBLIC_BASE_PATH=/budget/ .
docker run --rm -p 3000:3000 -e BUN_PUBLIC_BASE_PATH=/budget/ budget2
GitHub Pages
Pushing to main builds and deploys to Pages automatically, using
/<repository-name>/ as the base path. Enable Pages with "GitHub Actions" as
the source in the repository settings.
Your data
Everything is stored in this browser's IndexedDB. Export regularly from Settings → Your data: the JSON export is both your backup and how you move your budget to another device. Import replaces everything and downloads a backup of your current data first.
Known limitations
- Data is per-browser. There is no account and no sync. If you clear this browser's site data, or move to a different browser or device, your budget is gone unless you exported it first. The JSON export is not just a nice-to-have backup — it is the only way to move a budget between devices.
- The install prompt is incomplete.
manifest.webmanifestcurrently only ships an SVG icon. Chrome requires PNG icons at 192×192 and 512×512 to offer the "Install app" prompt; until those are added, the app works fine as a regular tab but won't be installable on Chrome/Chromium.
