/* ===================================================================
   PURE LUNG (+ HemoPrime) — custom design system
   FIRST lung/respiratory site; also first combo product (spray + capsule)
   Palette: airway-blue #0e3a53 | fresh aqua #3bb4c4 | cream #f4f8f9
            deep navy #0a2a3d | stone #5a6570 | line #dde7ea
            warm coral #e8654f (heart/cardio accent)
   Display: 'Onest' (clean, friendly modern) -> fallback Poppins/system
   Body:    'Inter Tight' -> fallback system
   Signature: breath flow (rising airflow curves — clear breathing / oxygen)
   NOTE: all grids minmax(0,1fr); flex items min-width:0;
         images capped with min(NNNpx,100%); hero mobile order H1->img->rest.
   PureLung = oral SPRAY (4 sprays/day). HemoPrime = CAPSULE (1-2/day).
   Kit images landscape (480x293).
   IMPORTANT: honest framing. Source had aggressive claims ("root cause",
   "restore in <1 month", "reclaim youth", "no side effects, all ages",
   "rigorous clinical testing") -> NOT reproduced; structure-function only.
   Respiratory/circulation SUPPORT; no asthma/COPD/heart-disease treatment
   claims. Individual ingredients have traditional/research roles, finished
   formulas not independently clinically tested. Doctor-consult + pregnancy/
   medication warnings. "FDA Registered Facility". Meta description <150.
