📝 Walkthrough

Walkthrough

Modified the benchmark dashboard status display to add helper functions for DOM updates and restructure multi-series status rendering. Now displays per-series deviation metrics and conditionally lists "focus" series based on parity band status, replacing a single-line message.

Changes

Cohort / File(s)	Summary
Benchmark Dashboard Status UI .github/bench-dashboard/index.html	Added setStatusText() and compactSeriesLabel() helper functions. Refactored updateStatus() to compute per-series deviation, build structured status UI with summary and focus list (up to 8 series), and set status class based on parity band detection. Updated error handler and added CSS for status list styling.

Poem

🐰 Whiskers twitched at the dashboard's glow,
Status updates now steal the show,
Focus lists sorted by deviation high,
Parity bands beneath the sky,
The bench board hops with info so neat! ✨
