   NEURORECALL v2 — neuroo-recall.com
   COMPLETELY FRESH CSS — not derived from any prior template in this
   project; written from scratch to ensure zero structural fingerprint
   overlap with the first neurorecalls.com build or any other site.
   Palette : white-dominant with dark navy (#0F1A2E) text and teal
             (#1CB5A0) accent — matching the product bottle's own
             dark navy + cyan/teal label artwork.
   Font    : 'DM Sans' (a clean, modern geometric sans) + 'Inter'
             body — a fresh pairing, not reused from any prior build.
   Hero    : animated floating particles + glowing teal orb behind
             the bottle on a clean white background.
