/* Direction contract
THESIS: Quiet bathhouse product page — water as care tool, not a medical story; refuses cream-maternity advertorial and scarcity funnels.
OWN-WORLD: Indigo mist ground, Source Serif 4 + Figtree, seafoam CTA, cedar hairlines; product photography only.
STORY: Visitor sees Lansinoh wash bottle, price 59 PLN, seller identity, then buys via BEBE Concept checkout.
FIRST VIEWPORT: Ad bar → brand → headline + line → price/CTA → full-bleed product plane.
FORM: Onsen water ritual (grounded #4, seed cf096b36, degraded roll).
