/* The secure portal's own stylesheet — small, and the only one it loads.
 *
 * NOT app.css and NOT office.css, deliberately. Those two carry the household's
 * and the office's frames, their nav, their controls and their fonts, and a
 * counterparty must never be handed a page that a stranger could mistake for
 * (or mine for) either application's chrome. The portal borrows the office's
 * TOKENS — the same ink, paper and slate, the same serif for headings — so a
 * recipient who later sees the office's own letters recognises the hand
 * (screens_brief §01), and it borrows nothing else.
 *
 * No web fonts and no asset from any other origin: the security checklist
 * (design_brief §08) forbids third-party assets on portal pages, and a test
 * scans every template and this file for one. System fonts only.
 *
 * Class names are portal-prefixed: templates outside office/ and house/ are
 * measured as classic house bodies by tests/test_kit_collisions.py, and a bare
 * `btn` or `card` written in one would be a word a house body wears. The
 * doors' templates (prove.html, signin.html) write a handful of bare words of
 * their own — kicker, lede, help, door, code-field — and the block at the foot
 * dresses those, scoped under the page they belong to.
 *
 * Themes are tokens: the light palette on :root, the dark one under
 * prefers-color-scheme (unless data-theme="light" pins it) and again under
 * data-theme="dark", so a future toggle wins in both directions. Nothing here
 * sets data-theme — there is no script for it — the hook simply exists.
