/* ---------- partner accreditation row ----------
   Reversed-white badge artwork sitting directly on the dark hero with no
   container. Held at 72% opacity so it reads as provenance rather than
   advertising, and comes to full strength on hover.

   The three PNGs are pre-normalised (see tools/build-partner-badges.py): each
   is scaled so its type has the same cap height, then padded to one canvas
   height with the text blocks aligned. That is why a single `height` lines all
   three up — do not size them individually, and re-run the build if the art
   changes. Reminder: 1rem = 10px in this theme, so these are set in px. */
