/*
 * ACM Command Hub's look, "D+ · Minimal, with a signature", for Team Desk (2026-09-28).
 * The hub's colours and type, light and dark, are in tokens.css: an exact copy of the hub's packages/ui/src/tokens.css
 * (acm-command-hub), loaded first, so Team Desk never depends on the hub being up. tests/test_tokens.py checks the copy
 * against the version recorded there; when the hub's look changes, copy the file across and update that record.
 * This file holds the frame's own styles, and the "bridge" names that give the pages the hub's colours in light and dark.
