/* ============================================================
   SESIMPEL WEBSITE LAYOUT
   Sits on top of sesimpel.css. Adds web-only structure (nav,
   sections, grids, marquee, accordion) without introducing a
   sixth colour, a radius, or a blurred shadow.

   Reason for every deviation from the poster system:
   - Fluid clamp() type: web has no fixed canvas, so type scales
     between a 360px phone and a wide desktop.
   - Sticky nav and a MENU text toggle: web chrome. The toggle is
     a word, not a hamburger icon, to respect "no icons".
   - Disclosure caret on dropdowns and FAQ: a functional UI
     affordance, drawn from two borders, not an icon.
