/* ═══════════════════════════════════════════════════════════════════
   Vidyalaya — public website.  2026 refresh.

   The identity stays: blackboard green, brass, and the four house
   colours strung across a section like sports-day ribbon. What changed
   is the execution.

   · OKLCH colour with tints derived by color-mix(), so the greens sit
     evenly against each other instead of being picked by eye.
   · Scroll-driven reveals with animation-timeline: view(). No JS, no
     IntersectionObserver, no library.
   · Cross-document view transitions between pages.
   · A real fluid type scale. The hero headline is set as one optical
     unit with tight tracking rather than a stack of sizes.
   · Dark mode, honoured from the visitor's own system setting.
   · Borders traded for whitespace and a hairline of elevation.

   All of it degrades: on an older browser the page is the same page,
   without the movement.
