/* VORLUX Academy — design system, RE-SKIN 2026-10-27 + owner corrections
   2026-10-27 04:28 (palette + real mascot + alignment discipline).
   Design LANGUAGE mirrored from the owner's two references:
   - Duolingo (de.duolingo.com): chunky buttons with a solid bottom edge
     (press = translateY + edge collapse), answer states (selected
     #ddf4ff/#1cb0f6, right #d7ffb8/#58cc02, wrong #ffdfe0/#ff4b4b),
     swan borders, 2px card borders, radius 12–16, bold rounded type feel,
     path rows with solid node badges, pill tabs.
   - Zertifly (zertifly.com/fr): deep-navy brand headings, near-white
     background, white cards, "glass" ring shadows, one colour per skill,
     exam-package colour bands, dark navy footer.
   PALETTE = THE OWNER'S LOGO, dominant everywhere (owner correction):
   electric blue #2E9BFF → cyan #38E1FF → violet #7C5CFF. Reference green
   survives ONLY as the semantic "correct answer" colour. Skill accents
   are drawn from the logo family + tasteful complements.
   Default theme = BRIGHT; the dark variant keeps the same shapes and is
   opt-in via the header toggle. No libraries, no webfonts.
   Transform/opacity animation only. */
