/**
 * Page header used to display the page/product the user is on.
 *
 * It has two mutually-exclusive left-side modes:
 * - `title` mode (default): shows a plain page title.
 * - `back` mode: when `backTo` is provided, the title is replaced by a
 *   "Back to <previous page>" button that emits `back` when activated. This is
 *   intended for when the user navigates a level deeper (e.g. worklist →
 *   detail view).
 *
 * The right side is a flexible content-projection slot: consumers project any
 * actions they need (e.g. `rivButton`, `riv-menu`, navigation arrows) into the
 * `[actions]` slot.
 *
 * The component owns its own horizontal gutter (`--size-large`) so it can be
 * dropped directly at the top of a page without a wrapper. Place it as a
 * sibling of (not nested inside) the page body — the body's own padding will
 * align with the header's.
 *
 * For visual consistency across pages, prefer `ghost`-variant `rivButton`s for
 * actions so they read as equal-weight, low-emphasis controls. Reserve heavier
 * variants (`primary`, `danger`) for a genuine primary action.
 *
 * ```html
 * <riv-page-header title="Patients">
 *   <button rivButton [variant]="'ghost'" actions>Add patient</button>
 *   <button rivButton [variant]="'ghost'" actions>Settings</button>
 * </riv-page-header>
 * ```
