/*
 * NepseIQ — Market Map
 * ───────────────────────────────────────────────────────────────────────
 * Geometry is computed in JS and written as absolute left/top/width/height,
 * so nothing here positions a tile. These rules only decide how a tile looks
 * once it has been placed, and the page chrome around the map.
 *
 * Tokens come from style.css. No gradients, no shadows, no rounded slabs —
 * the colour of the tiles is the entire visual language of this page, and
 * anything else competing with it makes the market harder to read.
