CLAUDE.md, AGENTS.md, ARCHITECTURE.md and TODO.md all said no browser exists
in this environment, so appearance had never been verified by anyone. Chrome
is on PATH. Its own --screenshot flag is what fails: it fires on the load
event, before this app's async IndexedDB read resolves, and captures a blank
page — which is presumably how the claim took hold.
scripts/screenshot.ts drives CDP instead: waits past the load event, seeds
IndexedDB via --eval-file and reboots the app with --reload, clicks with
--click, applies shadcn's class-based dark palette with --dark, and reports
console errors and uncaught exceptions. A page that renders blank from a
thrown error looks identical to an empty one, so the console output is half
the value.
Two defects found by simply looking:
- The month table's numeric columns had no horizontal padding, so figures ran
into each other: "+7,175.00 DKK4,200.00 DKK". Now padded.
- Dev logged "The script has an unsupported MIME type ('text/html')" on every
boot, because registerServiceWorker asks for sw.js and the "/*" catch-all
answered with the HTML shell. Dev now serves an inert worker.
Confirmed working, first time seen: the carry meter (including red where a post
is overspent), the Task 5 rule-history editor, the Task 6 "change from here"
control, and baked FX rates showing as "manual - 2026-09-01" in Settings.
Recorded in the docs, with the limits stated: this container's fontconfig maps
every generic family to a monospace face, so screenshots need a FONTCONFIG_FILE
override or you will chase a font bug that does not exist; Chrome starts from
an empty profile each run; and no screenshot can judge how a design feels.

TODO recorded these as needing a human because binary assets cannot be
generated in the agent environment. That turned out to be wrong: Chrome is on
PATH here and rasterizes the SVG exactly, so scripts/make-icons.ts generates
them and the output is committed. Verified pixel-accurate against src/icon.svg
before trusting it (background #0f172a, bars #38bdf8, underline #e2e8f0,
transparent rounded corners).
The generator uses an explicit Bun.spawn with a timeout rather than a shell
template, because Chrome did not always exit on its own here.
Both sizes now appear in the manifest, get copied into dist, are served by the
dev server, and are listed in the service worker precache — along with
icon.svg and manifest.webmanifest, which were also absent from it because the
list is derived from bundler outputs and these are written separately. Without
that an installed app could not render its own icon offline.
src/icons.test.ts checks the committed files are genuine 8-bit RGBA images of
the right dimensions by inflating IDAT and asserting the exact pixel-data
length, so a truncated or stub file cannot pass. It cannot detect staleness
if src/icon.svg changes — re-run the generator.
