             cream #F7F4EF | mist #EFEAE3 | slate #6A6470 | line #2A2530 (dark) / #E4DED4 (light)
   Type    : 'Fraunces' — NOT reused; this build uses 'Sora' (precise geometric display)
             + 'Inter' (clean neutral body) -- fresh pair, not used before
   Motif   : synapse pulse — a neuron-to-neuron connection that fires along
             branching dendrites, echoing the brand's own circuit-neuron artwork
   Layout  : dark hero (first dark-base hero in this project) with a faint
             circuit-line backdrop; image RIGHT.
   IMPORTANT: H1 sizing kept moderate on purpose (previous build's H1 was
   flagged as too large) -- capped well below prior builds' clamp max.
   Rules   : grids minmax(0,1fr) · flex min-width:0 · img max-width min(Npx,100%)
             mobile hero order = IMAGE first, then H1, then rest (unchanged)
