/* Pre-app screens (login, magic-link callback), styled to match the landing page so signing in feels
   like part of the same product rather than a bare form bolted onto it.
   Palette and type scale are lifted from landing.html; the tokens are duplicated here on purpose so
   this file stands alone (the landing page is one big self-contained document, not a shared sheet).
   NOTE: no webfont link — the site CSP is font-src 'self' data', so a Google Fonts <link> is blocked
   and would silently fall back anyway. The system stack below is the intended rendering. */
/* LIGHT IS THE DEFAULT, and the accent is the app's rose.
   Two things were wrong here. The accent was a blue the product does not use anywhere — every page
   served off this sheet (sign in, pricing, account, terms, privacy, the callback) looked like a
   different company to the app it signs you into. And the theme followed the OPERATING SYSTEM,
   while index.html follows data-theme and defaults to light, so a visitor on a dark desktop got a
   light landing page and a dark pricing page in the same click.
   So: light on bare :root, dark only when asked for explicitly or by system preference where the
   page has not asked for light. Same three-state shape the landing uses. */
