What changed in the port

Which parts became utilities, which stayed CSS, and why.

  • The activity feed is a two-track mini-grid (dot, text) — the same discipline as the rail rows, and the reason the bullets stay aligned when a line wraps.
  • The chart's aria-label states the trend and the range, not just the chart's name; a label that says 'bar chart' tells a screen-reader user nothing.
  • Product upgrade: KPI deltas gained direction glyphs and comparison periods, the chart card gained a target line in its header, and the panel became a real feed with named accounts instead of two sentences about overflow.

How this works

Two levels of grid. The shell owns the chrome; the body runs its own grids for the KPI strip (auto-fit) and the chart/feed split. Only the body scrolls.

Height overflow is the unintuitive half. Everyone remembers minmax(0,1fr) on the column; forgetting it on the row is why app shells grow a second scrollbar the first time a feed gets long.

Make it yours

  • Icon-only rail at a breakpoint: md:grid-cols-[56px_minmax(0,1fr)] plus md:hidden labels.
  • The KPI strip is standard RAM — add cards and they flow.
  • Add [scrollbar-gutter:stable] to the body so layout does not shift when content passes the fold.

Gotchas — read before shipping

  • Exactly ONE region scrolls; nested scrollbars make wheel behaviour unpredictable.
  • A CSS bar chart is decorative — ship an accessible table behind it, the aria-label is a floor not a solution.
  • Keep the rail's track fixed or clamped; a fluid rail plus a fluid body fights over every pixel.

App-frame geometry is original grid; scrollbar-gutter (optional) needs Safari 18.2+.
