/* Product pages (Aram, Bunnie, Vandelay, the products hub). Builds on
   /styles.css (fonts, tokens, HUD, cards). Each product sets its accent on
   its body class in its own stylesheet:
     --accent       buttons, rail, focus, core highlights
     --accent-rgb   the same colour as "r g b", for translucent borders
     --accent-2/-3  the heading gradient's middle and end
     --accent-ink   text on an accent background
     --accent-hover primary button hover
   Unlike the home page, sections flow normally: the scene stays fixed
   behind them and changes formation per section. */
