   BUTTRESS OS — SHOWROOM SKIN
   Architecture Practice OS · Accelerated Experiences LLC

   Palette note: warm bone + graphite + brass. Deliberately NOT the retired
   blue/navy brand (SSOT Art. VII.2). Reads like a drafting room, not a
   dashboard template. Tenant palette is swappable via the Skin Machine.
