/* ExactSky — celestial-atlas design system (front-end round, 2026-08).
   Two schemes: deep-night navy + starlight gold (dark, default) and white + navy + bronze
   (light). Display serif for headings/editorial, system sans for UI. Class contracts are shared
   with the admin pages (.panel/.tbl/.btn/.admin-nav/.stack) — restyle, never rename.

   THEME MODEL (owner ask 2026-08-12): default follows the system scheme; the header toggle sets
   an explicit choice as html[data-theme="light"|"dark"] (persisted in localStorage by the tiny
   inline scripts in base.html). CSS therefore needs the light tokens TWICE — once under the
   system media query (guarded so explicit dark wins) and once under [data-theme="light"].
   KEEP THOSE TWO BLOCKS IDENTICAL; same for the scheme-dependent rules further down
   (starfield). An unsupported-JS visitor simply never sees the toggle (it's JS-revealed). */
