/* Chrome for fitness-ui's rider dashboard components (ActivityTotals,
   ActivityMonthBars, ActivityHeatmap, ActivityTypeSplit, ActivityBests). A
   sibling of one-web's rules, not a mirror: geometry uses the design
   system's spacing and radius tokens, colour uses sites' own.

   sites has no --brand-color token (checked against main.css's :root); its
   nearest equivalent is --color-accent, used throughout below. The tile
   layout itself - four across on desktop, two-up on a phone - needs no
   rules here: activity-totals.html and activity-bests.html render into
   .grid[data-columns="..."][data-tablet-columns="..."], which utils.css
   already styles. What's missing is the tile furniture and the three chart
   shapes: bars, heatmap and type-split rows.

   These blocks are divs, not sections: sites gives every <section> 5rem of
   padding-block for full-width tenant page regions, and a dashboard stacks five
   blocks rather than one. Spacing is owned here instead, and the heading rhythm
   uses h2's own --h2-padding-block hook rather than overriding the global rule. */

/* The value a native title= tooltip would take a second to show. Hover only,

   needs more than that, so showing them all at once collides into noise.
   Touch keeps the bar heights, which is the shape a small screen is read for.
   aria-hidden because the bar's title already carries the same figure plus the
   activity count to assistive tech, and the chart takes no tab stops. */
