 * keep -- and one of them (the share link) is destroyed forever if the user
 * fails to copy it. So they get distinct accents carried consistently across the
 * field, the button and the note, and the hierarchy is:
 *
 *   Copy share link   (strong red tint)   - critical; losing it loses the secret
 *   Copy status link  (soft amber tint)   - useful, not critical
 *   Create another    (grey)              - the quiet exit
 *
 * Tinted rather than solid: a solid red button directly above a red warning box
 * reads as heavy and muddles "important action" with "danger".
