/// S2 (Tier 1 visual fidelity): `PluriScreenHeader` — a 38-radius glass
/// hero with an aurora banner, a black scrim, two radial orbs, a 120px
/// watermark and a tri-gradient glyph badge — is not in the prototype at
/// all (`t4` never draws it). It is retired from all 4 roots that used it;
/// each root's ONLY title chrome is now `PluriRootHeader` (S1). Its
/// subtitle text was the one thing the hero rendered that nothing else on
/// these screens does — its absence is this suite's signal that the hero
/// is really gone, since the class itself is deleted and can no longer be
/// referenced by type from a test.
///
/// Pre-existing project constraint (see `pantalla_ajustes_test.dart`):
/// PluriGlassSurface paints a background over ListTile's ink layer, which
/// Flutter flags as a warning-level assertion, not a correctness bug.
