   ClickMagik — design system · DARK
   ------------------------------------------------------------
   One palette, taken straight off the logo: the black tile and the navy it sits on, the
   green swoosh, the gold wand, the blue arc, the red candle. Every surface reads from these
   tokens — landing page, student view, admin screens, modals, OTP boxes, lesson
   flowcharts — so the theme lives in this block alone.
   ------------------------------------------------------------
   Tints (--*-soft), their hairlines (--*-line) and the text that sits on them (--*-ink) are
   tokens too, which is why a component painted amber or red somewhere else needs no second,
   light-only copy of itself to stay readable here.
   Two names mean something slightly different from the set they grew out of: --brand-600 is a
   *fill* you hover into, --brand-700 is brand-coloured *text* on a dark surface. Nothing uses
   700 as a shadow.
