/* MV_BackButton — one treatment for every way back (#482).
   Formerly `.chronicle__back` and `.timeline__back`, which were the same
   declarations copy-pasted under two names. Quiet by design: an exit should
   never outweigh the content it leaves, so it stays muted text + a bare
   chevron and only warms on hover/focus. */
