/* Shared page system for sofluffy.ai marketing pages (pitch/, vision/, connect/).
   Apple-style minimalism: neutral white / light-grey bands, one idea per band,
   centred hierarchy (product line → headline → subhead → visual → details).
   The one expressive element is glass: a frosted nav and product screens shown
   as frosted panels floating over a slow, soft colour field.

   Every class is prefixed `a-` so it never collides with the product mockups,
   which keep their own (app-matching) class names and warm palette. */
