/*
 * Per-design stylesheet for the Cover (single-header) hero.
 *
 * Most single-header rules live in Web/Content/assets/css/stylesv2.css
 * (the global framework bundle every public registry loads via
 * _Layoutv2.cshtml). Carving them out wouldn't be a no-op: Cover
 * registries would lose those rules, and pre-existing Classic registries
 * that happen to nest a single-header somewhere would lose them too.
 *
 * Intentionally empty stub. The fn-5 epic guarantees Cover renders
 * byte-identical to its pre-change baseline for existing registries
 * (R6 zero-diff requirement). Cover-only visual tweaks would land here,
 * but adding rules now would invalidate that guarantee. Leave the file
 * present so the per-design stylesheet load path (Gifts2.cshtml emits
 * stylesv2-design-{name}.css for the active design) treats every design
 * uniformly: a follow-up PR can add cover-specific polish without
 * touching the routing layer.
