Aligned all dialog boxes to a consistent pattern: same shadow
(--shadow-dialog), animation (fadeUp 0.2s ease), button sizing
(py-2, duration-150), and hover effects. Added template type
indicator dot to CreateCapsuleDialog combobox. Removed accent
gradient bars from templates page inline dialogs.
File browser:
- Add shiki-based syntax highlighting (lazy-loaded, zero initial bundle
impact) with support for 30+ languages
- Cap highlighting at 2000 lines to avoid freezing on large files
- Pre-compute preview lines as derived state instead of re-splitting
on every render
- Add content-visibility: auto on code lines for off-screen skip
- Remove per-line CSS transitions (unnecessary paint on 5000 elements)
- Cap row entrance animations to first 30 entries
Capsules list:
- Pause auto-refresh polling when browser tab is hidden
- Add empty state for search with no results
- Fix error state not clearing on successful refresh
- Fix action menu positioning near viewport edges
- Disable create button when no template selected
Template field is now a filterable dropdown that fetches available
templates on dialog open. Selecting a snapshot auto-fills and disables
vCPU/memory inputs since they must match the original capsule config.
- New sandbox_metrics_snapshots table sampled every 10s (60-day retention)
- Background MetricsSampler goroutine wired into control plane startup
- GET /v1/sandboxes/stats?range=5m|1h|6h|24h|30d endpoint with adaptive
polling intervals; reserved CPU/RAM uses ceil(paused/2) formula
- StatsPanel component: 4 stat cards + 2 Chart.js line charts (straight
lines, integer y-axis for running count, dual-axis for CPU/RAM)
- Range filter persisted in URL query param; polls update data silently
(no blink — loading state only shown on initial mount)
- Split /dashboard/capsules into /list and /stats sub-routes with shared
layout; capsuleRunningCount store syncs badge across routes
- CreateCapsuleDialog extracted as reusable component
