/**
 * Pinterest First Editorial - Content components.
 *
 * Reusable cards, author metadata, archive/section headers, breadcrumbs and
 * pagination, plus the Phase 5 homepage module composition (hero, grids and
 * the promotion block). Homepage modules are pure compositions of the existing
 * components, so they live with them rather than in a separate stylesheet;
 * archive composition still belongs to the later archive phase.
 *
 * Phase 9 adds the provider-neutral advertisement slot wrapper. Ad slots can
 * appear on any view (header, article, homepage, archive and footer), so the
 * component lives here with the other cross-view components instead of in a
 * conditionally loaded stylesheet.
 *
 * The document footer navigation is a cross-view component for the same
 * reason: every view that renders footer.php can show it, so its small token
 * styling lives here rather than in a conditionally loaded stylesheet.
 *
 * All shared values come from tokens.css. Component-specific values with no
 * token are declared as local custom properties on the component root
 * (Docs/ARCHITECTURE.md, CSS Rules).
 *

 * Advertisement slots
 *
 * One provider-neutral wrapper for every canonical slot
 * (Docs/DECISIONS.md #11; Docs/ADS_AND_MONETIZATION.md #2, #4, #7, #8).
 * The wrapper is only ever rendered when a slot is enabled and has provider
 * output, so there is no empty container and no blank gap. A publisher
 * configured reservation height is applied as `min-height`: a slow ad cannot
 * shift the layout, while a taller ad is never clipped.
 *
 * The wrapper stays inside the content width, does not introduce a stacking
 * context and never floats over content, so it cannot obscure navigation,
 * headings or interactive controls.
