/* ══ THE DUMDUM MATHS DESIGN SYSTEM ════════════════════════════════════
   Chosen by Hrishi on 6 Sep 2026 out of three directions (DECISIONS §5).
   This is the only design system; every page uses these tokens and nothing
   else declares a colour.

   The idea: the page is a PLACE, not a document. DumDum is a lit, fuzzy,
   rendered character; flat shapes set beside him read as stickers stuck
   onto a photograph. So nothing here is flat. The ground has depth and a
   horizon, light falls from the upper left, surfaces are objects with
   weight, and the counters in a ten frame are things a child could pick
   up — because concrete before pictorial is the whole pedagogy
   (DECISIONS P6), and it should look like it.

   The signature is the counter: a real lit sphere with a highlight and a
   contact shadow, sitting in a tray with a rim. Everything else stays
   quiet around it.                                                       */
