  /* ---------- get Paredra (official store badges + one web button) ------ */
  /* Queue 0723 (Marcos-directed, supersedes 0718 §1): the four NATIVE
     platforms wear their OFFICIAL store badge art, unaltered, from source
     (Apple marketing toolbox, Microsoft badge service, Google Play):
       iOS  = "Download on the App Store"      Mac     = "Download on the Mac App Store"
       Win  = "Get it from Microsoft"          Android = "Get it on Google Play"
     Web (the SPA) is the ONLY custom button. One shared height token
     normalizes the row; every badge stays >= the 32px online minimum and
     the Microsoft badge keeps its built-in gray keyline (part of the
     official artwork — never stripped). */
