Astral.Image.Dev (Astral v0.1.3)

Copy Markdown View Source

Development-time serving for optimized Astral images.

During dev rendering, image components register deterministic transform manifests under the image cache directory and emit URLs under /_astral/image/. The dev server then generates cached files on demand and serves them with no-cache headers, mirroring Volt's dev-server style while keeping image semantics in Astral.
