/* Observation overlay skin, BrowserSkill family: colors/radius ride the BSK
   design tokens (--card/--border/--primary/--destructive/--ring/--radius,
   defined on the .bsk-obs scope root by bsk-tokens.nomodule.css — values
   mirrored from packages/ui/src/styles/tailwind.css). Layout-only here;
   component chrome (buttons etc.) comes from @browser-skill/ui plus the
   scope-prefixed utility sheet. The shell overlay layer is click-through, so
   the card and capsule opt back into pointer events themselves. */
