/* ---------------------------------------------------------------- reveal
   Gated on html.js (set by a one-line script in <head>). If JavaScript never
   runs, nothing is ever hidden — a broken script must not blank the page.

   BOTH rules are wrapped in :where() to force specificity (0,0,0). This is not
   cosmetic. `.is-in` sets `transform: none`, and it stays on the element
   forever — so at any real specificity it silently outranks every *later*
   state that wants a transform: `.panel--lift:hover` (0,2,0) would never lift,
   `.reviews__row:hover` would never slide, and `.build.is-out` (0,2,0) would
   lose both its opacity AND transform, killing the portfolio filter's exit
   animation outright. At (0,0,0) the reveal is the floor, and every hover /
   filter / reduced-motion rule wins over it, which is exactly the intent.
   Keep BOTH in :where() — zeroing only `.is-in` would let the (0,2,0) base
   rule win and nothing would ever reveal at all.                             */
