   Grid and lamp (Dom, 15 Oct 2026; tuned in Brand/Motion/grid-lamp-tool.html)
   initGrid() in main.js adds .gl-on on fine pointers without reduced motion; elsewhere the
   page is as before. Construction lines rest at a low opacity (--gl-floor, set per section
   after the lines draw in) and a soft lamp (190px) lifts them back to full (--gl-lamp, with
   each line's --lx/--ly). A barely visible 6-column grid is drawn inside each section and
   each painted block, above its fill and under its content; lines sit above every fill.
   Masked blocks (GL.masks in main.js) have no grid of their own, and those without a fill
   get the colour behind them below, so the grid and lamp pass behind them.
