 - On mobile (`max-width: 768px`), `.cc-tabpanel` remains the sole vertical scroll owner for every chart-bearing tab. Shared chart primitives (`Bar`, `StackedBar`, `Sparkline`, `LineChart`, `RadialGauge`, `Funnel`, `TokenSeriesChart`, and the Command Center recharts wrappers) must shrink within the tabpanel, keep non-zero usable height, avoid stretch/clipping artifacts, and never introduce a competing vertical overflow container.
 - Mobile chart text must not rely on min-content luck: bar labels, values, token-series axis labels, funnel headers, radial labels, legends, and chart tracks need explicit `min-inline-size: 0`, wrapping, or ellipsis rules so long model/agent/repo labels cannot crush the track or create hidden horizontal overflow in a real browser.
 - On tablet (`min-width: 769px` and `max-width: 1024px`), `.project-content`, `.command-center`, and `.cc-tabpanel` keep the same definite flex/min-height scroll-owner chain, while the live strip and chart grids collapse before they can create document-level horizontal overflow.
-- Command Center stat cards, overview chart cards, live strips, table wrappers, Team chart panels, token-series plots, system control cards, and gauge/chart cards share the same tokenized rhythm: `--space-3` gaps/padding for card-like surfaces, `--border-width` borders, `--radius-md` radii, and `--surface-1` backgrounds. Area-specific accents may use `color-mix(...)`, but layout, border, radius, text color, and motion must stay on design tokens.
+- Command Center stat cards, overview chart cards, live strips, table wrappers, Team chart panels, token-series plots, system control cards, and gauge/chart cards share the same tokenized rhythm: `--space-md` gaps/padding for card-like surfaces, `1px solid var(--border-subtle)` borders, `--radius-md` radii, and `--surface-1` backgrounds. Area-specific accents may use `color-mix(...)`, but layout, border, radius, text color, and motion must stay on design tokens, with the named 4px spacing scale (`--space-xs`/`sm`/`md`/`lg`/`xl`/`2xl`) as the canonical vocabulary.
 - The dashboard browser-layout smoke includes a `[data-smoke="command-center-charts"]` fixture that loads emitted lazy Command Center CSS and verifies representative recharts pie, line, and empty states at mobile (390×844) and desktop breakpoints. The fixture asserts non-zero chart and SVG heights, visible empty-state text, no internal/page horizontal overflow, and no chart-level vertical scroll owner before chart layout changes are considered verified.
