Room Detail

The room page a guest lands on after picking a result. A gallery with a large hero and clickable thumbnails sits beside the room title, size and sleeping arrangement. Below, an amenities grid and a description. The heart of the page is the rate plan selector — flexible, non-refundable saver, and bed & breakfast — each a radio card with its own nightly price and policy. Selecting a plan updates the sticky booking summary (nightly rate × nights + taxes) and the reserve button in vanilla JS.
