/* ==========================================================================
   LIONS LANE — design system v2 "Nocturne"
   Mark: unchanged Data Lion. Wordmark: Michroma.
   Type: Sora (display, light weights) · Atkinson Hyperlegible Next (reading) ·
         Atkinson Hyperlegible Mono (data) · Michroma (wordmark + labels only)
   Colour: Abyss canvas, Lane Blue kept for action, Glacier for highlights,
           soft paper text instead of pure white. Glow is light, not paint.
   Motion grammar: everything travels in the lane — enter left, exit right.
   Built mobile-first: base rules are for phones, min-width queries scale up.
