/* Each radio's id ends in -r<route> (or -rALL for the "All routes" option);
   when checked, show only the matching panel. This uses :has() on the
   shared .route-filter ancestor (rather than a plain "~" sibling selector)
   because the radio is nested inside a fieldset/label wrapper, not a direct
   sibling of .route-panels — a plain sibling combinator can't reach across
   that nesting, which was the bug that kept every panel hidden. :has()
   checks the whole subtree instead, so it doesn't care how deep the checked
   input is nested, and it still scopes correctly to each metric's own
   .route-filter (it won't match a checked radio belonging to a different
   metric's filter). With CSS disabled entirely, the display:none rule above
   doesn't apply either, so every route's chart and table show at once —
   nothing is hidden from a no-CSS or screen-reader-only reading of the
   page. :has() has full support in every current evergreen browser
   (Chrome/Edge, Firefox, Safari) as of 2026. */
