/* The Control Room.
 *
 * Written for two readers - the owner and one colleague - confirming a proposal, often
 * on a phone, often standing up. Three consequences show up in every rule below.
 *
 * Mobile first. Every layout here starts as one column and only widens at 40rem. The
 * proposal is 778 lines long; a table that needs sideways scrolling on a phone is a
 * table nobody finishes reading.
 *
 * The WORDING is the thing being judged, not the machine name, so the real phrasing sits
 * at full size and the canonical name is muted traceability text beneath it.
 *
 * Every control is at least 44px tall. A mis-tap on Accept is not a typo anyone notices.
 *
 * Tokens with the same fallbacks the other IQ views use, so this page cannot drift from
 * the rest of the product's theme.
