/* ── The two columns, each split in two ─────────────────────────────────────────────── */

/*
 * Equal widths rather than a wider NEW. The two lists are read in opposite directions — NEW is
 * scanned for something worth keeping, ACCEPTED is worked from the top — and giving either more
 * room implies a priority that changes through a stream (§9.4).
 *
 * "Equal" has to be enforced twice, and the two clamps below do different jobs. One unbreakable
 * 400-character question used to make its column 2410 px wide against the other's 623 px and
 * push the document sideways to 3166 px. All the numbers here are measured, not reasoned about
 * — `tools/layout-check.html`, which exists because jsdom has no layout engine and every test
 * in this repository was structurally unable to see any of it.
 *
 *   - `minmax(0, 1fr)` rather than a bare `1fr`, which means `minmax(auto, 1fr)` and floors the
 *     track at its content's width. On its own this keeps the two columns **equal** — and lets
 *     the content spill out of them: skew 0, document 3215 px wide.
 *   - `min-width: 0` on `.column` and `.panel` (below). A grid item has an automatic minimum of
 *     its own content too, so the track clamp alone only moves the problem inwards. On its own
 *     this fixes **both** symptoms, which makes it the load-bearing half.
 *
 * Keeping the redundant one is deliberate: it is what holds the columns to the same width if a
 * descendant ever reintroduces a minimum the clamps do not reach, and that failure is the
 * disorienting one — a queue that is visibly lopsided is harder to read than one that scrolls.
