   NERVE ZEN ULTRA — nervezenultrra.com
   Palette : ink #34495E (calm slate-blue) | ink-dk #22323F
             steel(=warm amber-wood accent) #C08552 | steel-dk #96652E
             sage(=muted sage-green) #8AA688 | stone #FAF8F4
             sand #F0EAD9 | slate #5C6670 | line #E2DCC8
   Type    : 'Fraunces' (soft, calm serif display) + 'Inter' (clean
             body) — a fresh pairing not reused from any other build,
             chosen for a "zen/spa" feel distinct from every other
             build's crisp sans-serif display type
   Motif   : the zen breath — a circle that slowly expands and
             contracts like a breathing exercise, with a thin guide
             ring and a few small calm-dots drifting slowly around it,
             looping on a slow inhale/exhale rhythm; distinct from
             every other signature used (no path-travel, no
             convergence, no draw-in, no line-graph, no vessel flow)
   Layout  : HERO IMAGE ON THE LEFT, soft slate/amber glow backdrop
   Section design note: each major section uses a distinct visual
             treatment — icon-cards for ingredients, a horizontal
             ribbon-list for benefits, a connected vertical timeline
             for how-to-use, and a two-column comparison callout for
             the "difference" section.
   Tone    : honest, non-exaggerated — published coverage of Nerve Zen
             Ultra genuinely disagrees across sources: some describe a
             fully disclosed 5-ingredient formula (Passion Flower,
             Marshmallow Root, Corydalis, Prickly Pear, California
             Poppy Seed), while at least one other source reports no
             ingredient disclosure at all for the same product. Refund
             terms are also described inconsistently (full refund vs.
             partial-refund-for-opened-product with customer-paid
             return shipping) across different published sources. We
             use the most detailed, specific source as our basis and
             flag both discrepancies plainly rather than picking
             silently. Not a treatment for diagnosed neuropathy or any
             other medical condition.
