/* ══ base.css — loaded by EVERY page before its own stylesheet ══
   One place for the rules that must be identical everywhere, so a page with
   its own CSS file can't drift (user decision 2026-09-09):

   • no browser tap-flash / long-press highlight on any control
   • nothing is selectable EXCEPT the AI's replies (and the Select-text sheet)
   • where text IS selectable, the highlight is the brand green, never blue
   • the address bar is tinted to the app paper colour (meta theme-color is
     set per page; this file carries the matching CSS colours)              */
