   style.css — application SHELL styles
   --------------------------------------------------------------------------
   Scope: header, quick-settings panel, bottom navigation, page-view routing
   container, shared controls (buttons / segmented chips / select / sr-only).
   Every feature page injects its OWN scoped stylesheet under #mkf-* when it
   mounts, so this file only has to style the shell + shared chrome.
   Themes: light · dark · OLED (pure #000000) — driven by html[data-theme].
