   C-opus55 — STRAIGHT ANSWERS (FAQ) · top of the #cell-convo ink band.
   Authored by Opy (Graveyard: Opy-i1), Oct 10 2026.
   The client's own FAQ, verbatim. Native <details> — works with no JS.
   Material language matches the convo band: stamped-steel rows, hairline
   seams, ONE red (the number + the open state), mono labels, display caps.
   Rhythm: title left / list right, the same L→R read as the convo block
   below it, closed by a machined hairline before "Start the Conversation".
