postxl

[skaile-development] Use when building, modifying, or extending a PostXL-generated app inside skaile-dev — platform/backend, platform/frontend, and (in progress) store/backend. Covers schema authoring (postxl-schema.json, schema/*.model.json, schema/*.enum.json), the regenerate workflow (bun run generate → pxl generate + tsr generate), the three modes for code changes (schema edit / custom blocks / new module), postxl-lock.json and ejection semantics, the dual backend+frontend verify loop, the pxl doctor/status/info toolkit, and the @postxl/ui-components primitives. Activates whenever you see postxl-schema.json, postxl-lock.json, generate.ts, or // @custom-start markers, or when the user mentions PostXL, regenerate, eject, or custom block.
