   App-level chrome only — reset, shell, header, section dividers,
   main wrapper, footer, utility, and app-scoped print rules.
   Component-specific rules (assistant-block, question-panel,
   ask-btn, thinking dots, answer-panel, etc.) live inside their
   own component <style> blocks per BUS standards §7.

   Phase 6 additions: editor layout modifier classes (.app--editor,
   .app-main--editor, .editor-panel) for /edit.html. The base .app
   shell is reused; the editor only widens the page and turns the
   main wrapper into a two-column grid.
