+- A releases card lets a platform's file carry an architecture: a Mac visitor is offered the `macos-arm64` file, not sent to TestFlight past it.

 ## 0.6.19 (2026-10-05)
 
 - A `kind: url` resource whose JSON is a releases manifest (`latest`, `versions` with per-platform `assets`, `channels` such as a package repo or TestFlight) renders as a download card: the file for the visitor's own platform first, decided in the browser, the rest and the channels folded. Written for redoal's public releases at dl.redoal.com (docs: content-reference, "A releases manifest").
