/**
 * PUBLIC CATALOG — PAGINATION, then THE ITEM DETAIL PAGE: the two-column
 * layout, the gallery (main image, nav arrows, thumbnail rail, cover picker),
 * the title / description / tags column, the read-only listing-state strip with
 * its price, channel and upstream-source chips, and the print-request form.
 *
 * FIFTH of ten sheets — after styles-browse.css, before styles-controls.css.
 * Read the load-order block at the top of styles.css before moving a rule
 * between sheets: the split is a contiguous slice of one original file and the
 * cascade depends on it.
 *
 * Pagination leads the file because it led this stretch of the original and the
 * split is contiguous. It is browse furniture, not detail furniture.
 *
 * The operator-only EDITABLE cards that render below the strip are in
 * styles-listing-cards.css (sheet 9), not here.
