/**
 * Product browse arrows (Entity Pager module, view: product_pager).
 * Fixed buttons pinned to the left/right edges of product pages.
 *
 * The arrow heads are drawn purely in CSS (no images, no font glyphs) using
 * the rotated-border technique, so the SHAPE and COLOURS are fully under our
 * control. Everything tunable lives in the variables below — change a value
 * once and both arrows update.
 *
 * The full link text ("‹ Previous" / "Next ›") stays in the DOM for screen
 * readers; only the drawn arrow is shown visually.
