   Brand baseline: Studio Brown #3d2c1f, Studio Blue #e0ecff, Georgia type
   Aesthetic register: Anagrama (architectural rigour as system) + Pentagram
   Deviation: Warm Off-White #f5f0eb on renders grid section.
   Rationale: high-contrast renders read better on slightly toned ground.
   Studio reference: Anagrama's use of toned papers in spatial portfolios.
