/* ── Reset & Base ──
   These are the only rules in this file that reach outside the landing page's
   own markup, so they are the only ones gated on `html.landing`. Everything
   below is class-based (`.nav`, `.hero`, `.feature-card`…) and simply matches
   nothing when this stylesheet is loaded on a page that isn't the landing page.

   The gate exists because this stylesheet is now shared: the documentation site
   renders the landing page as its home (apps/docs), and an ungated
   `body { background: var(--clr-ocean-deep) }` would repaint every doc page.
   `initLanding()` adds and removes the class; the standalone page carries it in
   its markup.

   `:where()` on the reset, and only on the reset, because it contributes **zero**
   specificity. A plain `html.landing *` scores (0,1,1) — higher than every
   single-class rule in this file, so the reset's `margin: 0; padding: 0` would
   beat `.btn { padding }` and `.section-inner { margin: 0 auto }` and flatten
   the entire layout. Wrapping the gate keeps the selector at the (0,0,0) the
   bare `*` had, which is what all 1000 lines below were written against. */
