/* naka-ai public look "ฟ้าใส" (clear sky), in the same house as Naka Studio
   (apps/studio/frontend/app/assets/studio.css): a sky-tinted blue ground, cloud-navy ink, Naka's
   own cobalt for accents and links, and the studio's orange kept for ONE job: buttons. Kanit for
   headings, IBM Plex Sans Thai for text. The hero opens on a clear shader sky with bright clouds
   (sky-gl.js over sky.css), the closing band shares the CSS sky, the clip library sits on a frosted sky band. Loaded LAST on every public page: it restyles what the
   page stylesheets lay out and adds the home page's own sections (st- studio menus, g- library,
   s- steps, t- trust, c- closing). Inner pages add ui-pages.css.
   Contrast (computed): ink on ground 12.9:1, --ink-2 5.7:1, --ink-3 5.2:1 (4.9:1 on the clip band), cobalt on --u-sky 6.1:1.
   Orange buttons carry dark text: white on #f97316 is 2.8:1, cloud-navy is 5.6:1. */
