/**
 * DFOMS Frontend — Sprint 6 visual system.
 *
 * Design brief: a dormitory group-ordering board for students placing a
 * quick order between classes on a phone — not a storefront. Two decisions
 * follow directly from that:
 *
 *  1. List rows, not product grids. Restaurant and product listings are
 *     compact horizontal rows (thumbnail + name + one action), the pattern
 *     of a canteen menu board or a delivery app's order screen — built for
 *     fast one-thumb scanning down a list, not for browsing square photo
 *     tiles the way a shop grid does.
 *
 *  2. Session-tinted interface. DFOMS runs on two real daily ordering
 *     windows (Morning / Evening). The list and menu pages pick up an
 *     amber tint when Morning is the live session and a dusk-plum tint
 *     when Evening is — driven by the actual `session_type` the API
 *     returns, not a decorative theme switch. A student glances at the
 *     color and already knows which window they're ordering in.
 *
 * Type is set entirely in the system font stack. This app is read in
 * Vietnamese, Traditional Chinese, and English on the same screen, often
 * on modest Android phones over dorm wifi — a display webfont would
 * either miss CJK glyphs or cost a network round trip neither of those
 * conditions can spare. Personality comes from weight and spacing instead.

 * ShortcodeRegistrar::enqueue_assets(), which checks has_shortcode()
 * before loading it) - so every rule below can only ever take effect on a
 * DFOMS ordering page, never on any other page of the site. A theme or
 * WooCommerce may still render its own breadcrumb, mini-cart widget, or
 * "Continue shopping" notices around the page content on the SAME page a
 * DFOMS shortcode was placed on; those are unrelated to the dormitory
 * order flow and only add visual noise/confusion (a second, unrelated
 * "cart" concept next to DFOMS's own cart), so they're hidden here.
