/* ==========================================================================
   Sparqle design system -- calm LIGHT theme (default) + opt-in night theme
   ([data-theme="dark"]).

   Foundation rebuilt to pixel-match the founder's design files (Sparqle
   Design System / M2 / M3 references): a cool cream ground (#F9F9F7),
   near-black espresso ink and PRIMARY BUTTONS (#0B0B0B on white -- never
   gold), white cards, a terracotta/clay brand accent (#C6613F family), and
   the four-point gold spark (#F0A63A) reserved as a SPARSE accent: the
   logo glyph and mastered/current trail stones only. Subject accents stay
   the design's muted earthy set (clay math, sage science, ...).

   Every color flows through a token, so both themes flip cleanly from the
   two blocks below; component rules never hardcode a theme-specific color.

   The previous dark-terminal treatments (neon text glows, scanlines,
   terminal traffic-light dots, blinking block cursor) are retired:
   --glow-text-sm and --scanlines-soft resolve to `none` in both themes,
   --glow-box resolves to a soft shadow, and the terminal-only ornaments
   paint nothing. The one earned ceremony (sparkleBurst on mastery) keeps
   its gold warmth in both themes -- see sparkle.css / sparkle.js.

   Type: headings are Nunito 700 (titles) / 600 (subtitles), never below
   20px. The design names Fredoka, but Fredoka has no glyphs for
   c/d/e/n/r/t-caron or u-ring, so per the founder (2026-10-28) Fredoka 600
   is used ONLY for the ASCII wordmark "MaStezka" (--font-wordmark) and
   Nunito carries every heading (Fredoka 600 -> Nunito 700, 500 -> 600).
   DM Sans for body (17-18px, line-height 1.55), buttons (700 16px pill)
   and labels (700 12px uppercase, 0.08em). --font-mono is a legacy token
   name kept because templates reference it inline; it resolves to DM Sans.

   Fonts are vendored locally under app/static/fonts/ (Fredoka latin only,
   Nunito, DM Sans; all SIL Open Font License 1.1, see
   app/static/fonts/OFL-LICENSE.md); latin + latin-ext subsets only. No
   external CDN font references (GDPR + offline dev).
