Always-visible trend lines next to the existing bars on every running instance and static-site card so the user can spot a slow drift or recent spike at a glance, without expanding the full history chart. Implemented as a tiny pure-SVG component (no ECharts on hot list paths) — values are fetched once per 30s alongside the current snapshot via a 30m history query that the collector already serves. - Sparkline.svelte: pure-SVG polyline + optional area fill, normalises values to [0,100] and clamps out-of-range points - ContainerStats: parallel fetch of stats + 30m history, two new $derived arrays for CPU% and memory%, sparklines slotted between the bar and the numeric readout
