  Capacitor Toolkit — standalone PWA
  ------------------------------------------------------------------
  This tool shares the same independent design tokens as the resistor
  toolkit (see the :root block below, carried over from the site's
  capacitor-toolkit.css), separate from the --tbc-* tokens the
  bias/tone-stack tools share. We alias --tbc-* to this tool's own
  token names so the shared app-shell/install-gate layer works
  unmodified and still matches this page's real palette.

   APP SHELL — standalone PWA layer
   ================================================================== */

/* ======================================================================
   Shared PWA app-shell layer — canonical source
   ----------------------------------------------------------------------
   Generic standalone-app chrome shared by every DiMastro GTA PWA
   (safe-area insets, .install-gate, .tbc-db-notice, and related
   install/offline UI). Written against the --tbc-* custom properties;
   each app's own :root block (in its own css/_head.css) either
   declares --tbc-* directly, or aliases its own token names to them.

   DO NOT EDIT apps/<name>/css/styles.css directly for anything in this
   section — edit this file instead, then run:
     python3 apps/_shared/sync-apps.py
   to regenerate every app's actual served styles.css. Edits made
   straight to a generated styles.css will be overwritten on next sync.

   Tool-specific widget CSS (the calculator itself) lives in each app's
   own css/_head.css and is untouched by this file or the sync script.
