/*
 * Querlyn website and account portal stylesheet.
 *
 * Identity: light and editorial — a bright canvas, generous whitespace, a soft gradient mesh behind
 * the hero, Geist for text with Instrument Serif italic accents in display headings, and the desktop
 * app's dark terminal (#10141b, mint accent) inside product illustrations. The page follows the
 * visitor's light or dark preference. One brand accent (teal); red and amber appear only as status
 * colours (errors, draft notices). Fonts are self-hosted (/static, SIL OFL): no external requests.
 * Every text pair meets WCAG 2.2 AA (4.5:1) in both themes; borders of form controls and focus
 * rings meet 3:1.
 *
 * The page CSP forbids inline styles, so pages use these classes and element styles only.
 * Shared vocabulary for the account pages: form elements, `.button` / `button` (primary) and
 * `.secondary`, `.notice` and `.notice.error`, `.card`, `table`, `.muted`, `.visually-hidden`.
 * Layouts: `.portal` (signed-in pages with a sidebar), `.auth` (sign-in and similar, one centred
 * card), `.prose` (documents).
 *
 * Spacing uses longhand margins on components so a component class never cancels the spacing
 * of a layout class it is combined with (e.g. `class="section notice"`).
