   Plant Doctor — marketing site stylesheet (v2, scripted rebuild 2026-08-22)

   Doctor's office, not emergency room: calm forest tones — the urgency lives
   in the words. Layout breathes more as the page descends. Amber appears
   ONLY on the pet-safety mention. Light-only. No external fonts/frameworks.
