   Type    : 'Spectral' (refined literary serif) + 'DM Sans' (clean geometric body)
   Motif   : fullness expansion — a soft circle that slowly expands outward as
             concentric rings "absorb" into it, on scroll, tied directly to
             Konjac Glucomannan's real fiber-expansion mechanism (distinct
             mechanic from every prior gauge/pulse/rhythm/dose widget)
   Layout  : HERO IMAGE ON THE LEFT (desktop), soft flowing ribbon-stroke
             backdrop behind the copy column for a visibly distinct hero
             composition (liquid-drop / ribbon motif, not used before)
   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)
