Morphing download button
Transforms from download action to determinate transfer rail and verified package state. Activation advances an accessible progress value, then exposes a completed checksum state. It is a three-stage transfer control rather than an indeterminate loader or copy confirmation.

Accessibility notes
- Every interactive target is a labelled native control with a visible focus treatment.
- State changes are communicated through a polite text status and never by color alone.
- The contained visual effects stop when the user requests reduced motion.
