/* ---- Project grid -------------------------------------------------------
   Each tile is a flat colour square with the project name underneath. The
   icon is a *background image* rather than an <img> on purpose: until the
   file exists the browser paints nothing and the flat colour stands on its
   own, where a missing <img> would show a broken-image glyph. So adding an
   icon later is a file drop into assets/tiles/ with no markup change.

   The label sits under the square, never on it, so tile colours never have
   to pass a contrast check against text — and the name stays readable when
   the page is zoomed, which is the standing rule for this site.           */
