/*
 * FotoGrids - Collection Header (back button + breadcrumb trail)
 *
 * Stylesheet for the .fg-collection-header block emitted by the
 * Collection_Header feature module. Sits inside the gallery wrapper,
 * above .fotogrids-filters.
 *
 * Theming-friendly defaults:
 *   - Uses `currentColor` so themes can recolour just by setting `color:`
 *     on the parent.
 *   - No background, no padding by default - sits as text-like chrome.
 *   - No hard-coded font; inherits from the surrounding content.
 *   - Wraps cleanly on narrow viewports.
