Negative remaining balances are shown in a warning treatment; nothing
blocks going over budget.
Applies the Tasks 18-23 design contract: --paper/--ink/--rule/--accent/
--surplus/--overspend tokens and the three type-role font variables in
src/index.css, --font-money on every money figure, and the carry meter
(a 3px hard-stopped gradient beneath each PostTable row) encoding
carried-in surplus, allocation track, spend fill and overrun.

Base path comes from BUN_PUBLIC_BASE_PATH so the same bundle serves both
a root Docker deploy and a GitHub Pages subpath.
Deviation from the task-16 brief: does not install @happy-dom/global-registrator,
does not create test/setup.ts, and does not add a [test] preload to bunfig.toml.
A global DOM preload would make src/domain/smoke.test.ts's "importable without a
DOM" assertion vacuously true, silently retiring the check that guards the
domain-layer-stays-pure invariant. Nothing in this task needs a DOM: basePath.test.ts
is pure string logic, and the shell render test was intentionally omitted by the
brief itself. A later task will register happy-dom per-file where a DOM is
genuinely required.
Generated in-browser with fflate, so export works offline. mimetype is
stored first and uncompressed as the ODS spec requires.
Also adds datasetMonthSpan to the domain views layer, which determines
the month range an export should cover: from the fold start through
the latest month touched by any month record or purchase slice,
including future finance-plan slices.
Widened the mimetype-header test's byte slice from 64 to 96 bytes: the
zip local-file header for "mimetype" is 38 bytes and ODS_MIMETYPE is
46 characters, so 64 bytes could never contain the full string
regardless of implementation.
bun init --react=shadcn, with the demo API routes removed since this app
has no backend. Adds project invariants to CLAUDE.md and a smoke test
proving the domain layer imports with no DOM.
