/*
 * RahkarTheme — rahkar/products-slider (frontend + shared).
 *
 * The card visuals come from the shared rahkar-product-card stylesheet
 * (.rpc-card*). This file only owns slider-level concerns:
 *
 *   • track layout: flex row + CSS scroll-snap
 *   • arrow buttons (desktop + mobile)
 *   • "view all" tail item
 *   • heading + responsive scaling
 *
 * Design choices:
 *   • Item width is derived from `--rps-cols` (desktop) and `--rps-mob`
 *     (mobile fractional). Touch users can still swipe; arrows are an
 *     additional affordance, not a replacement.
 *   • RTL-correct: rail order follows DOM order under the parent `dir`,
 *     and we use logical properties for padding/offset so "next" lands
 *     visually on the leftward side in RTL.
 *
 * Item width formula:
 *   flex-basis = (100% - gap × (N - 1)) / N
 *
 * Mobile uses N = 2.5 by default → 2 full cards + half of the next, a
 * built-in "scroll me" affordance for swipe-first users.
