   COLOR SYSTEM
   All colors reference CSS custom properties defined on :root.
   Never use hardcoded hex values anywhere in this file.
   Light mode only — dark mode intentionally removed per design preference.

   IMAGES TO COMPRESS BEFORE DEPLOY
   Run all images through squoosh.app or imageoptim before pushing:
     /assets/hero/*.jpg          → target < 300 KB each (1920px wide max)
     /assets/wedding/*.jpg       → target < 200 KB each (1200px wide max)
     /assets/tokyo/*.jpg         → target < 200 KB each
     /assets/commercial/*.jpg    → target < 200 KB each
     /assets/studio-co/*.jpg     → target < 200 KB
     /assets/about/headshot.jpg  → target < 150 KB (900px wide max)
