Eight docs under docs/ covering the current design: the WithProps mixin
and lifecycle, the PropDef/attribute model, the leaflet-register bubbling
protocol, generic event forwarding and its typing, per-component special
cases, the load-bearing export order in src/index.ts, and the toolchain
(TS 7, oxlint, oxfmt, Vitest, the no-bundle build, dual npm/JSR publish).
Also wire docs/**/*.md into the format script and point at docs/ from
CLAUDE.md and README.md.
