/*
  The Multiamory account portal.

  # The palette is the app's, not a second one

  Every colour below is lifted from `ui/input.css`, which is RADAR's design system and the place
  those values are decided. The portal previously carried its own invented purple, which meant the
  sign-in page and the app it signs you in to did not look like the same company — the exact
  problem this rebuild exists to fix.

  Three role rules come with the palette and are easy to break by accident:

  - **Violet is primary. Buttons are never red.** Brick Red also signals errors, so a red button
    reads as "something has gone wrong" no matter what its label says.
  - **`--danger` is for warnings and destructive things only**, never for emphasis.
  - **Dark is not a tint of light, it is the opposite.** On dark the accent becomes Flax — a bright
    warm CTA on a near-black Violet field — and the ink flips. Redefining only the tokens is what
    keeps that from turning into two stylesheets.

  # No inline styles anywhere

  The content-security policy in `functions/[[path]].ts` is `style-src 'self'` with no
  `unsafe-inline`, because this origin can enrol passkeys for the whole of `multiamory.com`. A
  `style="..."` attribute added later will silently stop rendering rather than fail loudly, so if a
  page ever looks unstyled, that is the first thing to check.
