   1. PAGE GRID

   Three columns, three rows. The key move: breadcrumb and hero occupy the
   CENTRE column only, in rows 1 and 2. The side columns are empty until
   row 3, so both sidebars begin below the hero instead of alongside it.

     ┌─────────┬──────────────────┬─────────┐
     │         │ breadcrumb       │         │  row 1
     │         ├──────────────────┤         │
     │ (empty) │ hero: h1, dek,   │ (empty) │  row 2  ← first viewport
     │         │ highlights, img  │         │
     ├─────────┼──────────────────┼─────────┤
     │  TOC    │ article body     │  rail   │  row 3  ← sidebars start here
     │ sticky  │                  │ sticky  │
     └─────────┴──────────────────┴─────────┘

   Sticky (not fixed) is what makes them scroll into place and then hold.
   The old `position: fixed; top: 60px` is why the TOC sat on top of the
   header and breadcrumb at scroll-zero.
