   B5 — STICKY META COLUMNS
   A left meta column that scrolls away while its content keeps going wastes
   the one thing the reader needs while reading: what they are looking at.
   Held in place instead, clear of the floating nav.
   ========================================================================== */

/* The text column of every category block — factory and containers — holds
   while its image scrolls past. Only these: I first wrote this against
   .model-hero__meta and .page-head__aside, neither of which exists on any
   page, which is a rule that does nothing and reads as if it does something.

   Sticky and a scroll-reveal transform do not mix — a transform on the
   element makes it its own containing block and stickiness stops working —
   so the reveal's transform is dropped here. The reveal has finished long
   before anyone scrolls past. */
