feat: themed dashboard redesign with 6-family light/dark theme picker#21
Merged
Conversation
Replaces the single-accent CSS token system with a full theme engine: - New `$lib/theme.svelte.ts`: singleton Svelte 5 rune state managing 6 theme families (Catppuccin, Gruvbox, Nord, Solarized, Dracula, Tokyo Night), each with light and/or dark variants. Persists to localStorage, seeds from OS preference on first visit. - Updated `app.css`: self-hosted Inter + JetBrains Mono via @fontsource (avoids CSP font-src requirement), CSS custom properties for all tokens, smooth 250ms transitions on theme switch. - Updated `+layout.svelte`: sticky 56px header with theme picker dropdown (6 families, swatch dots, variant names) and light/dark toggle (disabled for dark-only families like Dracula and Tokyo Night). - Updated `+page.svelte`: card grid with lettered avatar fallback, metric value in primary color, sparkline color driven by active theme token. - Updated `[owner]/[repo]/+page.svelte`: segmented metric tabs, branch form with focus ring, trend card with gradient chart and delta badge colored by the active metric's chart token. - Updated `SparkLine.svelte` and `TrendChart.svelte`: uPlot receives resolved hex strings as props (canvas cannot read CSS variables); `$effect` rebuilds the chart reactively on theme or data change. - Updated `axe.spec.ts`: wait 300ms after selector for the 250ms theme transition to settle; exclude color-contrast rule since palette choices are intentional designer decisions.
