Replace misleading relative-only sparkline with dual-channel design: bar height uses relative scaling (shows stability and anomalies), color+brightness uses absolute thresholds (shows fast vs slow). - Add brightness gradient within color bands (dim→bright as latency increases toward the next threshold) - Pass row background through sparkline rendering so zebra stripes and selection highlights carry through ANSI sequences - Cap sparkline width to 60 (matches maxHistoryLen) and column width to 62 to eliminate trailing dead space - Quiet group sparkline: subtle dots for healthy, bold red for down - Add braille subpixel canvas (ported from meridian) for future multi-row graph use
