Hosting-provider tokens for IFP-21 hosted_on

Hosting-provider tokens for IFP-21 `hosted_on`

This entry defines the token vocabulary for the hosted_on field of an IFP-21 locality declaration. Each token names a hosting provider — optionally qualified by region where the regional distinction is the point of declaring it. Declarations use the token, not the display name.

A declaration's hosted_on list means: the declaring principal's agent services and data stores physically run on these providers. Locality is a distinct axis from legal jurisdiction (IFP-21, Section 4).

Token	Provider
`aws`	Amazon Web Services
`azure`	Microsoft Azure
`cloudflare`	Cloudflare (Workers, Pages, R2, and related services)
`digitalocean`	DigitalOcean
`fly-io`	Fly.io
`gcp`	Google Cloud Platform
`hetzner-eu`	Hetzner, EU data centers (Germany and Finland)
`netlify`	Netlify
`ovh-eu`	OVHcloud, EU data centers
`self-hosted`	Hardware operated by the principal (home server, office rack, colocated machine)
`vercel`	Vercel

Conventions

Tokens are lowercase ASCII letters, digits, and hyphens, in the manner of IFP-22 handles.
A region-qualified token (hetzner-eu, ovh-eu) is used where the region materially changes the locality picture; an unqualified token means the provider without a region claim.
A principal whose infrastructure spans several providers lists several tokens.
To add a token: open a pull request adding a new version of this entry with the token and its provider row. The new version supersedes this one; citations to this version remain valid.
