/* Aeron Studio.

   Built to sit next to higgsfield.ai rather than next to aeron.sh: near-black
   canvas, media-first cards at 16:9, Space Grotesk set uppercase and tight for
   every label, Inter for prose. Those are the measurements taken off their own
   page — #0f1113 behind everything, surfaces at #1c1e21, card titles at 16px /
   700 / -0.04em uppercase — because a generation gallery reads on dark and a
   white page makes every render look like a document.

   The one thing not borrowed is the accent. Theirs is lime #d1fe17; this is
   Aeron's own #09f875, in exactly the same role. It is one token below. */
