/* warm-clinical — gutadvice.com V1.6
   Design intent: feels like a thoughtful doctor sitting across from you.
   Palette: cream background, deep teal accent, terracotta highlights.
   Type: Fraunces (optical-size serif) + Inter (sans body).

   V1.6 layout (per founder 2026-09-11 11:14 UTC: "Use layout of V1.2"):
   - Hero is back to V1.2's 2-col grid: eyebrow + headline + lede + ctas
     in the left column, the GI tract illustration in the right column.
   - The .illust-section that V1.4 added below the hero is removed.
   - On mobile, the hero stacks vertically (1-col).
   - The illustration is the PR #8 GI tract (V1.5) — clinical line
     drawing with 7 organ labels (MOUTH, ESOPHAGUS, STOMACH, SMALL
     INTESTINE, LARGE INTESTINE, RECTUM, APPENDIX). */
