Env variables

Pro

Environment variables as an editable table: names checked as you type, secrets masked and never shown again after saving, per-environment checkboxes, paste a whole .env file, and one save bar that counts the changes.

Accessibility #

It exposes region, alert and status semantics, with aria-labelledby, aria-hidden, aria-label, aria-invalid, aria-describedby and aria-pressed kept in step with state. Changes that matter are announced through a live region.

Keyboard and focus handling comes from Radix dialog: arrow keys move through items, Enter and Space select, and Escape closes and returns focus.

Motion #

Transitions use the shared duration and easing tokens. Under prefers-reduced-motion those tokens collapse to instant and travel distances go to zero, so state changes still happen without movement.
