Device + Browser alignment

1. Web preview and LVGL should use the same profile ID names.
2. If a profile is unavailable on one side, fall back in this order:
3. noto-sans-mono
4. noto-sans
5. system fallback
6. For strict pagination parity, test with noto-sans-mono first.

Packaging recommendation

Install the exact TTF/OTF files used by browser preview and badge firmware in a shared asset bundle so font metrics remain stable across targets.
