/* Home — Treatments (client round, 2026-10-26: "the most important section on the home page").
   Three layers, one hierarchy:
   1. three photo cards for the most requested treatments (the lead one wider)
   2. a navy band in the patient's own words: "I'm in pain" -> Root canal
   3. the four specialties, every treatment a chip; on desktop a sticky panel shows the hovered
      treatment's photo and, where a patient wrote about it, a verbatim line of their review.
   Markup: services.js homeTreatments(). Logic: tx.js. No backdrop-filter, transform/opacity only. */
