/* The conversation (docs/decisions.md, 10 Oct 2026, "The conversation on both order pages"): what
   the two sides wrote to each other, in chat order. The reader's own side on the right as an ink
   bubble, the other side on the left outlined; a proof as a small card; a decision as outlined
   chips; the small words under them quiet. A staff note is drawn apart in the staff look, tinted on
   a dashed rule with "Only Ativv sees this" on it, so it can never be taken for a line the customer
   read. */
