/* Larimar Miner — "Tide" Authentic & Look-Alikes page (comparison-led, bright system).
   Page-specific classes prefixed .t-auth-. Reuses :root tokens + shared classes from tide.css
   (.t-display, .t-eyebrow, .t-eyebrow--diamond, .t-contact-band). Square corners, hairline
   borders, no shadows on light. The five look-alike images are deliberately TINTED PLACEHOLDERS
   (no real calcite/aragonite/howlite/turquoise/chrysocolla photography) — the per-mineral
   gradients + texture overlays match the design comp. */
