/* ============================================================
   TRT PERFORMANCE MEN'S HEALTH — Octopuss-AI preview rebuild
   Re-skinned in the Linear design system ("midnight precision
   instrument"): near-black layered surfaces, hairline borders,
   Inter variable at 400–590, one chromatic action color.
   The action color stays the clinic's own brand red #B9080C
   (their logo/site accent); coral #eb5757 is its text-safe
   twin on dark. Every line of copy is sourced from
   trtperformancemh.com. No invented names, stats or reviews.
