/* PACT Brain — on-brand styling.
   Brand palette (sourced from pactfoundation.com / gov.pactfoundation.com design tokens):
     --pact-purple  #AB48DA   primary brand / CTA
     --pact-indigo  #121668   deep indigo (headings)
     --pact-navy    #0B0C2B   near-black navy (bg base)
     --pact-muted   #66677D   muted text
   Telegram themeParams are still read (app.js) for hint/link niceties, but the
   PACT brand identity is applied deliberately so the app looks on-brand in any
   Telegram theme (light or dark). */
