/* Ambio Edge — light/dark theme layer.
   Dark is the base design (inline <style> on each page). This file adds:
   the theme toggle button, the light token set, and light overrides for
   hardcoded dark colors. Theme is set on <html data-theme> by the inline
   head script before first paint; see /theme.js.
   The "GENERATED" block below is produced from the pages' inline CSS by
   scripts/gen-theme-css.py — rerun it after adding hardcoded colors to a page. */
