Google Fonts COS Demo

Two loader variants — pick one to open the demo.

• Static loader SHA-256 hashes are pre-computed at build time and baked into the script. Fastest on every visit; requires a rebuild when Google updates a font file.
• Dynamic loader No pre-computed hashes. Re-fetches the Google Fonts CSS every 24 hours; font version strings in URLs act as automatic cache keys, so updates are picked up without a rebuild.
