/* my-deepagent Web GUI — v0.2 PR #3 polish pass.
 *
 * Visual reference: modern dev-tool dashboards (Linear / Vercel /
 * Resend / Railway). Goals:
 *   - Refined dark palette (deeper background, soft surfaces)
 *   - Card-based layout with clear hierarchy
 *   - Pill badges for run / phase state
 *   - Tabular numbers for metrics, monospace for IDs
 *   - 8 px spacing grid, generous padding
 *   - Subtle hover / transition without animation chaos
 *
 * Vanilla CSS only. No build system. No CSS-in-JS.
