/* ============================================================
   ScolerAI — about.css
   The About page: the dashboard's own arrangement, brought to the site.
   A greeting on the photograph (the home page's fixed backdrop, on the
   same hour), then ONE rounded, opaque sheet rising over it that carries
   the reading, then the sign-off back on the photograph.

   Layers, per the Spatial Tactile Glass principles:
     Layer 0 · the photograph (home.css `.backdrop`)
     Layer 1 · the sheet — SOLID white. §5.2: never glass under long
               paragraphs; §7.2: content is the reference plane.
     chrome  · the fixed header, frosted only once the page has moved
               (`.chrome--stuck`, home.css).

   Type: Poppins for headings, Inter for reading, Space Grotesk for the
   eyebrows (the app speaking), JetBrains Mono for the two award years.
   Every figure is HTML + inline SVG so it renders in all four locales.

   Expects home.css (tokens, backdrop, chrome) and foot.css before it.
