clapointe-carbonleo moves Mike off Cloudflare and onto Vercel

The headline change is a hosting move: this fork was built to run on Cloudflare, the network-and-hosting provider, and the team rewired it to run on Vercel, a rival platform popular with web teams. Files now stay on object storage while the app itself lives on Vercel. If you're weighing the same switch for your own Mike deployment, this is the most reusable part of the work.

The rest is house-specific. The interface got a full reskin in CarbonLeo's brand - dark backgrounds, an olive-gold accent - and the per-user API key settings were dropped. To stand the thing up quickly, the team also tore out login and access control wholesale; some real authentication was bolted back on later, but per-document and project-sharing permission checks are still stubbed out.
