   Type    : 'Spectral' (precise, medical-adjacent serif) + 'Lexend' (clean readable sans)
   Motif   : glucose gate — a vertical slatted barrier with a molecule dot passing
             through in a controlled, animated rhythm on scroll (ties directly to
             the "Barrier" name)
   Layout  : HERO IMAGE ON THE RIGHT (desktop). Backdrop uses faint vertical gate
             slats rather than blobs/diagonals/gradients used in prior builds --
             a genuinely distinct hero composition.
   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)
