/* boyaki.css
   Styles for 「ぼやきボタン」 -- the floating voice-grumble feedback button
   (js/boyaki.js builds the DOM this styles; nothing here is in any page's
   HTML). Shares css/app.css's design tokens (--accent/--danger/--surface/
   --ink/--border/--radius/--tap-min/--focus-ring/--shadow) so dark mode and
   the 40-50代 high-contrast/large-tap-target requirements come for free --
   see that file's header. Loaded on all four pages. */
