   adhd-study-pack.css — standalone styles for the study pack app.

   Self-contained rather than built on style.css: the app is a tool,
   not a page of the portfolio, and it wants a calmer, lower-contrast
   surface than the marketing pages. Design choices are deliberate for
   the audience — restrained motion, one clear focal point per view,
   and nothing that moves unless the reader started it.
