/* ---- Orbit Ring motif ----
   A conic-gradient arc, never a numeric badge - fill + color together
   read as a status at a glance (trust level, Experience status, or
   Discover match strength). Stroke width is a fixed fraction of the
   ring's own size so it reads as a deliberate ring at every scale,
   not a hairline. The inner disc's background follows --ring-bg so it
   blends into whatever surface it sits on (paper, card, or elevated
