/**
 * Products element renderer (shared).
 *
 * Phase 1, step 29. Handles both `products` and `product_carousel` element
 * types via a single renderer:
 *
 *   - element type `product_carousel` ⇒ caller forces display_mode='carousel'
 *     and dispatches here (see the case in impulse-page.php / impulse-preview.php).
 *   - element type `products` honours `display_mode`: 'grid' (default),
 *     'carousel', 'single'.
 *
 * Pre-extraction differences resolved:
 *
 *   - The two parent files had divergent `impulse_render_product_card`
 *     signatures (frontend's 4-arg modern vs editor's 20-arg positional).
 *     That helper now lives in `_product_card.php` with the frontend's
 *     signature as canonical; every call site here passes a `$product`
 *     object directly.
 *
 *   - Editor's `product_carousel` case shipped extra "effect" modes
 *     (`fade`, `card_flip`, `depth_rush`, etc.) that the live frontend
 *     never had. Dropped — designers were previewing effects that didn't
 *     ship to production. carousel_mode collapses to either 'snap' or
 *     'scroll' (the two modes the live frontend supports).
 *
 *   - Editor's renderer fabricated 4 hardcoded sample products when the
 *     DB returned none. Preserved here only in editor context so the
 *     builder still shows realistic-looking cards on a blank page.
 *     Frontend just renders nothing when there are no products (matches
 *     the published-page behavior of "block disappears when empty").
 *
 *   - Editor pre-resolved `columns` / `gap` against `$impulse_preview_device`
 *     and rendered only that one device's layout. Frontend emits CSS for
 *     all three breakpoints and lets the browser pick. Unified: both
 *     contexts emit the @media rules now (editor preview gains live
 *     responsive flow on iframe resize — matches the animator/header
 *     direction we agreed on).
 *
 * @sideeffect Sets $GLOBALS['impulse_needs_carousel'] when display_mode is
 *             'carousel', so the carousel JS loader knows to enqueue.
 * @sideeffect Calls `wp_add_inline_style('instinctor-page-inline', ...)`
 *             with the grid/carousel responsive CSS.
