/* ═══════════════════════════════════════════════════════════════════
   SPARKUNA STUDIO — the staff theme for every page in the CH Sparkuna menu
   (2026-10-10, Alif: "a Sparkuna design system for all Sparkuna pages")
   and TH /my-students (2026-10-10).

   MASTER: shared-design/sparkuna-theme.css. The CH + TH copies are synced
   by `npm run sync:tokens -- --apply` and held byte-identical by the
   check:tokens pre-commit gate — never edit a hub copy.

   Source: the Google Stitch design system "Arcade Academic" (Stitch project
   "Eduversal Students Hub — Game Home", 4481946878143943737), which is the
   look students see on www.sparkuna.com: deep cosmos canvas #0f0b24,
   Electric Violet #6c5ce7 (lip #4834d4), Cyber Cyan #00f2fe (lip #0891b2),
   Starlight Gold #ffd32a (lip #f5b301), Streak Ember #ff793f / #ff5252
   (lip #d63031); Outfit for headings + numbers, DM Sans for body; chunky
   buttons with a solid bottom lip that press down.

   Staff edition: the hero + section rail keep the dark cosmos; the working
   area is a light "moon paper" so tables and long forms stay easy to read.
   Neon cyan / gold are used on dark only — on light they become their
   readable "ink" shades (WCAG AA for text).

   Use:  <body data-theme="sparkuna" data-page-accent="sparkuna">
         <header class="page-hero" data-accent="sparkuna">…</header>
         <nav class="spk-rail" data-spk-rail></nav>      (filled by sparkuna-shell.js)
         <link rel="stylesheet" href="sparkuna-theme.css"> after shared-styles.css
         Outfit in the Google Fonts link.
