   HORSE BOOST — custom design system
   2nd men's-vitality site, but DISTINCT from Horse Gelatin (burgundy/
   crimson/gold, Anton, capsule). This one: athletic navy/electric-blue/
   volt-lime, sporty ANGULAR performance style, POWDER product.
   User asked for "some different style" -> angular clip-path accents,
   skewed ribbons, bold sporty vibe.
   Palette: navy #0f1b3d | electric-blue #2f6bff | volt-lime #c6f24e
            deep-navy #091027 | cream #f4f6fb | stone #5c6478 | line #dde3ef
   Display: 'Chakra Petch' (technical sporty) -> fallback 'Rajdhani'/system
   Body:    'Inter' -> fallback system
   Signature: strength ascend (rising power bars — endurance/strength)
   NOTE: all grids minmax(0,1fr); flex items min-width:0;
         images capped with min(NNNpx,100%); hero mobile order H1->img->rest.
   Product is a POWDER (stir-in, once daily, 30 servings).
   IMPORTANT: men's wellness. Structure-function ONLY:
   - NO ED/medical/disease claims; strength/stamina/energy/recovery support.
   - Source says "FDA Approved" BUT also admits supplements aren't FDA
     approved -> use "FDA Registered Facility", NOT "FDA Approved".
   - Ingredient dosages NOT disclosed -> generic roles only.
   - L-Arginine -> circulation/BP/heart/nitrate-ED-med interaction note.
     Ashwagandha -> thyroid/immunosuppressant/sedative/pregnancy note.
     Tribulus -> hormone-sensitive-condition note. Doctor-consult.
   - Individual ingredients researched; finished formula NOT clinically
     tested. Softened unverifiable ratings. 60-day guarantee. Meta <150.
   - Aff link is a third-party affiliate tracking redirect (flagged once).
   - "Horse Boost" is a brand name; NO false "horse-derived" claims.
