/* Threads panel — a left-side companion to mastra's CopilotSidebar.
Every surface, border, radius, and type ramp here is lifted from CopilotKit's
V2 design system (@copilotkit/react-core/src/v2) so the panel reads as the
same product as the chat on the right:
- surfaces: white card on a white app; borders are the --border hairline
- radius: --radius (0.625rem) for rectangular controls; rounded-full
(999px) for icon buttons, the segmented control, and the New-thread
affordance — echoing the sidebar's close button, suggestion pills, and
send button
- type: 0.875rem base / font-medium / tracking-tight, matching the
sidebar header + pills (no heavy 700 weights)
- primary action color is the sidebar's near-black --primary, NOT a brand
accent — the V2 sidebar's primary buttons render bg-black/text-white */
