   THE INSTITUTE FOR UNFATHOMABLE HAPPINESS — STYLESHEET
   Design language: flat colour, hairline rules, symmetry, restraint.
   No gradients, no drop shadows, no border-radius soup — consistent with
   the brand guide's own "what to avoid" list (see project brand guide).
   Type: Zilla Slab (display, Archer-in-spirit) + Jost (body/UI, Futura-in-spirit)
