   Two independent systems, because they answer different questions:

   1. On load    — the hero and page headers are already on screen, so they
                   animate immediately, staggered by position. See `.hero .wrap > *`.
   2. On scroll  — everything below the fold waits until it is actually seen.
                   `[data-reveal]` is hidden by CSS only under `.js`, so with
                   JS off the page is fully readable.
