/*
 * The server-rendered pages: sign-in and the allauth family, the error
 * pages, the public home. One small sheet, no framework.
 *
 * Every colour below is a token from frontend/src/design-system/tokens.css
 * (dark palette) so these pages are visibly the same product as the React
 * screens behind the door. Keep them in step: a palette change lands there
 * first and is mirrored here.
 *
 * Form markup is what crispy-forms' bootstrap5 pack emits (.mb-3 /
 * .form-label / .form-control / .form-check / .invalid-feedback / .alert),
 * styled here directly — Bootstrap itself is not loaded.
