- Replace text 'Collapse'/'Expand' button labels with Lucide chevron SVG
icons (chevron-down expanded → click to collapse, chevron-up collapsed
→ click to expand). Matches the iconographic design language of the
rest of the chrome (composer buttons, sidebar controls).
ARIA label + title attributes carry the same semantics for assistive
tech, so no accessibility regression vs. the text labels.
- Fix collapsed-card edge clipping at viewport bottom. Original
.clarify-card { bottom: -24px } was sized for the expanded card
(300-420px tall); adding a 72px collapsed variant pushed the header
below the parent's visible region. Override bottom to 8px and reduce
inner padding for the collapsed state so the entire header sits cleanly
inside the viewport at both desktop and mobile sizes (verified card
fits with ~115px margin desktop / ~125px margin mobile).
