- ui: add uptime% chip (green >=99, red below) after ssh; remove "up" word - ui: all shadows use #0004 shadow-color; modal shadow-lg derives from it - ui: status modal draws a datetime tick mark every 20 history entries from the newest - server: drop max_points/downsampling/bucketing; metrics served raw, plots share a ~24h window - docs: fix ps --no-headers in top example; document raw metrics API - server: inject <meta name=title/description> into index.html from config title + per-group host patterns (shared with --check recap)
