Fathym Reference Runtime (@fathym/runtime)

Runtime-focused utilities layered on top of @fathym/common: deno-kv helpers, fluent interfaces, OAuth/JWT helpers, worker/service primitives, and tailwind-focused utils.

• Goal: host runtime-level building blocks while keeping @fathym/common lean.
• Outputs: runtime library exports, build/test tasks, and integration docs for downstream runtimes and CLIs.
• Code location: projects/ref-arch/reference-runtime/.

Current Status

• Modules moved here from @fathym/common: deno-kv, fluent, oauth, services, workers, and tailwind-oriented utils.
• Entry point mod.ts exports runtime modules via src/.exports.ts; tasks defined in deno.jsonc.
• Adjust imports in downstream packages to target @fathym/runtime for runtime helpers.
