Place Thematic Group screenshots here when ready.

Expected files:
- `hero.webp`
- `before-home.webp`, `after-home.webp`
- `before-about.webp`, `after-about.webp`
- `before-mobile.webp`, `after-mobile.webp`

Pages use graceful placeholders, so missing images will not break anything.
See `../PROJECT_IMAGES_GUIDE.md` for how images are wired in `src/data/projects.js`.
Use honest screenshots only — no fake metrics, testimonials, or outcomes.
