/* =========================================================
   p.a. studio: HOMEPAGE (2026-10-05). Spec:
   AMAA-Brand/studio/brand/BRAND-UPDATE-2026-10-05.md
   Direction from studying ManvsMachine, Buck and Malvah:
   one typeface, black and white with the work bringing the colour,
   the work is the page, small fades with a job, one next step.

   Colour (v4, Patrick 2026-10-05): 60% Cloud White #FAFAFA, 30% Jet #312F2C,
   10% Moss green #3D5A3B. White is the page (hero, work, contact, sheet);
   Jet is the "How I work" band and the footer band (the moody stills add
   to the dark share); green is every call to action, every link and one
   highlighted word per heading. On Jet, green TEXT uses the lighter
   #8DB38A (Moss itself is too dark to read there); buttons stay Moss.
   Type: Instrument Sans for everything (section headings Bold 700, Patrick 2026-10-05); Instrument Serif italic for
   ONE word (the hero's "brand."). Bricolage only inside the logo.
   Shape rule: photos are square-cornered; buttons are full pills.
   Contrast: Jet on White 12.8, #66635F on White 5.7, Moss on White 7.3,
   White on Moss 7.3 (button), White on #4A6B47 5.8 (hover),
   White on Jet 12.8, #AAA8A4 on Jet 5.7, #8DB38A on Jet 5.7.
   z-index: nav 50, sheet uses the top layer (dialog), skip link 70.
