/* Polish 2026-10-13 (Impeccable critique item 1). Loaded last (index.html), so at equal specificity it wins; every
   rule is written twice — `:root .x` for the old Desk and `:root[data-board] .x` for the Board — to beat both homes.
   One token, --tap-min (desk-tokens.css): on a phone (≤600px) or any coarse pointer, every control's hit box is at
   least 44×44. Where the visual should stay small (avatar, "?"), the box grows and the drawn shape stays put
   (background-clip / a gradient disc), so nothing looks bloated. Desktop with a mouse is unchanged. */
