fix(fonts): wire fonts.css to actual Manrope + Opificio binaries

- Add @font-face for every Manrope weight 200-800 (incl. new Light/300)
- Map Opificio cuts to lowercase filenames as installed:
  * opificio_light/regular/bold.woff2 -> family "Opificio" (300/400/700)
  * opificio_light_rounded/rounded/bold_rounded.woff2 -> family "Opificio Rounded"
- Restore Opificio README with the actual file -> CSS-weight mapping
- Update Manrope README to list the installed weights
