   Architecture: a neutral, monochrome "shell" (Avemtis) that frames two
   venture panels, each carrying its OWN real brand palette:
     • F2 Visuals  — intentionally monochrome / cinematic
     • Roomify     — near-black with a signature mint accent
   All brand colors are SAMPLED from the live sites + logos (see comments
   on each token). No invented accents.
