  BT-007.6 Part A -- design tokens.

  What this is:
    Light + dark color palettes as CSS custom properties plus a thin
    typography / radius / spacing scale. The dashboard's component
    partials (templates/components/*.html) reference these vars so the
    light <-> dark swap is purely a color rebind -- layout, density,
    component sizes stay constant.

  Density rule:
    Light mode and dark mode use IDENTICAL spacing + sizing tokens.
    Workshop designers sometimes use dark = denser; we don't. The
    only difference between the two modes is which palette is bound.

  How to extend:
    Add a token here, then reference it via `var(--name)` in a
    component or template. Don't sprinkle hex codes in templates.

  Chart.js charts are configured with `responsive: true, maintainAspectRatio: false`,
  which means the canvas takes its dimensions from its positioned parent.
  Without an explicit container height the canvas balloons to fill the
  viewport on render, causing lag + the "empty plane" visual when the data
  arrives a frame late. Wrapping each canvas in .card__canvas-wrap fixes
  this by giving Chart.js a bounded box to render into.

  Sparkline canvases inside .kpi-tile__sparkline are NOT wrapped — that
  container already constrains height (see .kpi-tile__sparkline above).

  Three modifiers because charts have different ideal heights:
    --tall    Doughnut (chart-product-groups) — needs vertical room
    --med     Primary line/bar charts (daily revenue, weather, pool history, equity)
    --short   Compact bars (weekday averages, labor by weekday)
