/* ===========================================================================
   Word Search — layout on top of corner.css. Large-type letter grid, themed
   word list, tap-and-drag OR tap-first/tap-last selection. Colorblind-safe:
   found words are struck through with a check in the LIST (text cue), not
   signalled by grid color alone. Endless: every grid is generated fresh from
   themed word lists. Sizes via --cell (set by fit()).
