The “Lantern compatible” badge

For an implementation that passes the suite, at the level it reaches.

An implementation that passes the conformance suite at a level may show its badge: the Core one, and one for each further level it reaches, with the draft it passed. Only then (the name and the badge).

In a README

[![Lantern compatible 0.4 · Core](https://lantern.boreale.dev/assets/badges/lantern-0.4-core.svg)](https://lantern.boreale.dev/implementations/?utm_source=github&utm_medium=readme&utm_campaign=badge)

A badge says the draft it was checked against, and keeps saying it: with a new draft, run the suite again before you show the new one. The badges follow Boréale's brand: the frame in the aurora's colours around the night, the lantern in snow.
