/*
    app.css — the app's one stylesheet (F19, FR-17).

    Hand-written, no build step and no framework. The values are the landing repository's
    `src/assets/tokens.css`; the components are the parts of its `site.css` the app uses —
    header, footer, the plain page with one message, the form box, the search list, the
    reading page — as drawn for these pages in specs/2026-10-03/0-app-pages/draft.html.
    Provenance and hashes: static/README.md.

    `core/email_theme.py` is the emails' home of the same colours; tests/test_palette.py
    fails when a colour the two share differs. A colour changes in both, or in neither.
