   /account-memory · page-only styles, prefixed .am-. Tokens only, no raw colour.
   The first viewport is the moment: the memory list on the dark field is the
   control (pick one), the white chat beside it shows the day it was said and
   the fresh session weeks later where it came back inside a decision card.
   With JS off every thread is shown, stacked. One reveal (.rv) on the two
   stage blocks and the proof cards; js/account-memory.js owns the switch.
