Dsh Ui Outline

Key features

• The rail hugs the conversation column edge (the details panel never collides), centers on the live reading band, and hides below a 900px column — exactly like the shipped navigator.
• Scroll tracking reads one rect per frame and binary-searches cached turn offsets, refilled only when the conversation DOM changes.
• Design tokens (--dsw-alias-) resolve live from the host page with the official first-paint fallbacks, so theme changes and future token updates are picked up automatically.
• Every color, radius, shadow, and motion curve resolves live from the host's design tokens.
• Idle ticks rest perfectly aligned
