   NERVE ZEN ULTRA — nervezeenultra.com
   Palette : ink #2D5F3E (medium forest green, from the label) | ink-dk #1D4028
             steel(=warm coral-orange accent) #E8935A | steel-dk #C4703A
             sage(=soft leaf-green secondary) #8FC08A | stone #FAFBF6
             sand #F1F4E9 | slate #4F5A4A | line #E1E8D6
   Type    : 'Spectral' (elegant, refined serif display) + 'Inter'
             (clean body) — an intentional, editorial-feeling pairing
             per the standing instruction to raise typography quality
   Motif   : the calm wave — a jagged, restless waveform that smooths
             into a calm, even sine wave and back again, on a loop,
             echoing the "reduced discomfort / calming" positioning of
             the formula; distinct from every other signature used
             across this project (not a network of nodes, not a
             bidirectional pulse, not a bounce, not an arc-travel, no
             charge-bar, no kettle tilt)
   Layout  : HERO REDESIGN — same elevated template as the standing
             instruction going forward: diagonal two-tone backdrop,
             floating stat/trust chip overlapping the product shot, an
             angled/lifted product image with a soft ground-shadow,
             tighter vertical rhythm
   Voice   : confident, direct brand voice — Nerve Zen Ultra speaking
             for itself, benefit-first declarative sentences, checkmark
             bullets, clean enthusiastic FAQ answers. Compliance and
             disclaimer language lives in the footer, not repeated as
             hedging in every section.
   Tone    : Nerve Zen Ultra's 5 ingredients (Passion Flower, Marshmallow
             Root, Corydalis, Prickly Pear, California Poppy Seed) are
             the SAME underlying botanical formula sold under other
             brand names in this product category — fully disclosed,
             no proprietary blend, but no independently verified third-
             party review data exists for this specific finished
             product. This build does NOT fabricate a customer review
             count or star-rating stat, since the competitor research
             explicitly found none — testimonials are presented as
             seller-published experiences, not verified statistics.
             Strict structure-function language only; not a treatment
             for diagnosed neuropathy or any diagnosed condition.
