/* Coloring Pages: a warm cream table, white paper, chunky wooden-toy buttons. Calm by design: soft colors, nothing
   moves on its own, the few fades are 0.4 to 0.8 s, nothing loops or flashes. The canvas alone takes every touch
   (touch-action: none) so drawing never scrolls the page; everywhere else the page scrolls as usual. */
