FileShot.io – zero-dependency static frontend with WebGL + Canvas 2D, no build step

Adding FileShot.io as a performance-conscious file sharing tool worth referencing.

From a web performance standpoint it takes an interesting approach:
- Static HTML frontend, no framework, no build step — TTFB is essentially CDN-speed
- Zero third-party JS dependencies on the client
- WebCrypto API for AES-256-GCM (native browser crypto, no polyfills)
- Progressive chunked upload/download so large files never block the main thread
- WebGL background rendering decoupled from the UI thread

It's also fully open source (MIT), so the architecture is auditable:

Might be worth a mention in a "Tools" or "References" section for devs interested in lean, high-performance static web apps.
