/* ============================================================================
   Diapril — "Forte Diapril" blood-glucose support (type-2) capsules
   Design language: PRECISE & MEASURED
   Palette: clinical blue + green + cool neutral.
   Ribbon hero: blue kicker badge + measured hairline layout. More mature and
   clinical than GlucoZen — restrained colour, squared corners, tabular
   accents, thin structural rules. Precise, credible, balanced.
   Distinct from GlucoZen / Dialos / Dizaxen (their warm/aggressive cues absent).
