/* =============================================================================
   Vocabulary Quiz Engine — Design System
   =============================================================================
   Direction: a library card-catalog aesthetic. Vocabulary and dictionaries
   are the actual subject matter here, so the design leans on that directly
   rather than generic SaaS styling — a serif display face for questions
   (the way a dictionary entry reads), quiet card treatments with a thin
   top rule (like a catalog card), and A/B/C options as small lettered
   discs rather than loud colored buttons.

   Color/type tokens are CSS custom properties so dark mode is a single
   attribute swap ([data-theme="dark"] on <html>), not a second stylesheet.
   ============================================================================= */

/* --- Font loading -----------------------------------------------------------
   Self-hosted, not pulled from a CDN — consistent with this project's
   minimal-external-dependency stance (see project README). Font files
   are NOT included in this scaffold (binary assets); download and place
   them at the paths below. See internal/web/static/fonts/README.md for
   exactly what to fetch. Until then, the fallback stacks below already
   read as deliberate choices, not browser defaults, so the app looks
   reasonably composed even with fonts missing.

/* ==========================================================================
   Utility classes
   --------------------------------------------------------------------------
   These replace what used to be inline style="..." attributes in the
   templates. The Content-Security-Policy (style-src 'self', see
   internal/server/middleware/security_headers.go) forbids inline styles, so
   browsers silently ignored every one of them. Do NOT add 'unsafe-inline' to
   the policy and do NOT put style="..." back in a template (a test,
   TestTemplatesHaveNoInlineStyles, fails if you do): add a class here instead.

   Naming: the number in a spacing/size class is the value in rem with the
   decimal point removed (mt-075 = margin-top 0.75rem, maxw-26 = max-width
   26rem, fs-085 = font-size 0.85rem); an "n" means negative (mt-n05 =
   margin-top -0.5rem).

   !important is deliberate and confined to this block: an inline style beat
   every selector, and these classes must keep winning over component rules
   (e.g. a button's own padding) exactly as the inline styles did.
