/* STRUCTURES CLOSE UP ON THE TV (public/structure-focus.js; Lee, 20 Oct 2026: "i can click and show clients in
   high res each structure"): the studio's preview of the summary only. A row under each pathway, in the "along"
   row's own indent, of small outline buttons, one per structure. A button's state (data-state: sent, shown,
   refused, unsent) changes its colours only — the same border width, padding, weight and words in every state —
   so nothing on the page moves when the TV answers (Lee's rule). Shared rules only: no per-element custom
   property (WebKit keeps memory for each). */
