/* TCM The Present — Phase 2 Corrections
   =========================================
   This file patches base.css for mobile responsiveness and accessibility.

   Audit performed at 390px viewport (iPhone 14 / typical small phone width).
   Each correction references the issue identified in the Phase 2 audit.

/* ── Treatment Areas — square-card redesign ──────────────────
   Layout: two 4-column rows spanning the full container width.

   ROW 1 (.treatments-top-band):
     [Card 1 Women's Health] [Card 2 Dermatology] [Card 3 Internal Medicine] [Acupuncture image]
   ROW 2 (.treatments-bottom-band):
     [Card 4 Paediatrics] [Card 5 Urology] [Card 6 Pain Management] [Card 7 Geriatric Care]

   The heading + intro sit above both rows, centered, before the grid.

   Square cards: aspect-ratio 1/1. Content is flex-column from the top
   with enough padding to breathe. Font size is --text-body-sm for
   descriptions so that the longest card (Women's Health EN / Internal
   Medicine KO) sits comfortably inside a square without overflow.
   Overflow is handled by overflow: auto with a subtle fade rather than
   hard clipping — in practice all descriptions fit the chosen size.

   The image cell in row 1 is also 1:1 (matching the card squares)
   with a clean rounded frame (border-radius) instead of the blob shape,
   so it sits flush in the grid without visual imbalance.

/* ── Instagram button — redesigned ───────────────────────────
   Design: tasteful gradient treatment that reads as Instagram-
   branded while staying coherent with the calm blue healthcare
   aesthetic. The button uses the iconic Instagram gradient
   (purple-to-orange) as a background on the icon region, paired
   with a soft off-white pill body. The text colour is a dark
   warm-neutral for legibility on the off-white ground.
   An animated gradient-shift is gated behind
   prefers-reduced-motion: no-preference so it never fires for
   users who opt out.

   CONTEXTS:
   1. White contact sidebar card — off-white/gradient chip reads
      cleanly against white card background.
   2. Navy footer (#0A2540) — the chip pops against the dark
      background without becoming garish.
