   Related panel (M8 AI 工具联动) — the active scene's relationship table
   (CLAUDE.md §5.5). Floating-panel chrome (.panel-floating*) comes from
   style.css; this file only styles the body content (.rel-*).

   Uses ONLY existing design tokens (style.css §3.1 / v1 family) so it inherits
   light/dark and matches the ⌘K palette it shares a visual language with:
   --surface-1/2/3 · --ink-1/2-v1/3-v1 · --line-1/2 · --font-ui/mono.
   No new colors (DESIGN.md §3.5 monochrome).
