/**
 * v1.4.27 R3d MB1 — `<ResponsiveSheet>` primitive branch coverage.
 *
 * The primitive renders as a bottom-anchored `<Sheet>` on `<md` (768
 * px) viewports and as a centred `<Dialog>` on `>=md`. Every primary
 * form (Measurement, Mood, Medication) now mounts through the
 * primitive — opening the Add-Measurement dialog from `/measurements`
 * exercises the path end-to-end.
 *
 * The spec scopes itself by project name (Pixel 5 mobile vs Desktop
 * Chrome) and asserts on the `data-variant` attribute that the
 * primitive stamps onto its content node (`sheet` on `<md`,
 * `dialog` on `>=md`). The sticky-footer pin only exists on the
 * Sheet branch — assert it carries the documented sticky class.
