/**
 * v1.25.7 — the "Appearance" home (slug stays `layout`).
 *
 * The hub stopped being a link list: it now composes the dashboard, insights,
 * and every tracking module's settings inline as stacked, anchored sections.
 * Each module section keeps its module-gate (fail-open `!== false`), so a
 * disabled module's section does not render. These tests pin the composition
 * contract — anchors, headings, and gating — and mock the child section
 * components (each has its own dedicated test) so the render stays a pure
 * composition smoke.
