   Guarded behind html.js so content stays visible by default if
   JavaScript fails to load or run (progressive enhancement).
   Stagger delays for items inside a `.stagger` container are assigned
   inline by JS (see initScrollReveal) so any grid size stays covered
   without hand-written nth-child rules. */
