/**
 * The row-cap notice (spec: "Monetization Gates / row cap"). When the free
 * plan's per-layer row cap truncates a layer, the map still renders — so
 * WITHOUT this the failure is invisible to the person looking at the map, and
 * a partial dataset silently reads as a complete one. That invisibility was
 * the whole reason the gate used to render nothing instead (license.ts's
 * revised violation-mode note); this node is what makes truncation safe to
 * prefer over a blank layer.
 *
 * Deliberately NOT the badge's twin:
 *
 *  - Dismissible, and no tamper resistance. The badge is a CONDITION of the
 *    free license, so it fights removal; this is a diagnostic. Hiding it costs
 *    the viewer nothing but their own warning, and the dev/agent channel
 *    (`report`, severity "error") is unaffected either way.
 *  - Dismissal is keyed to the SIGNATURE of what was truncated, not to the
 *    session. Dismiss it and it stays gone for that situation — but a
 *    genuinely different truncation later (another layer, a changed count) is
 *    news, and says so again.
 *  - Top-center, because widgets own the corners.
 *
 * `update()` is called on every reconcile and must stay free when nothing
 * changed — it compares signatures before touching the DOM at all.
 *
 * ANNOUNCEMENT is a separate, permanently-mounted, visually-hidden live
 * region rather than `role="status"` on the visible box. A live region has to
 * already be in the accessibility tree when its content changes for assistive
 * tech to announce it — inserting a node that ALREADY carries
 * `role="status"`/`aria-live` usually announces nothing, and moving the
 * region's content into a `display:none` box doesn't announce either. So the
 * region mounts empty at map construction (long before any data loads) and
 * only ever has its text swapped. The visible box deliberately carries NO
 * live-region role, or the same message would be announced twice; it stays in
 * the a11y tree so its dismiss button is still reachable by keyboard and
 * screen reader.
