/* Base design system for the Baldwin City Historical Archive.
   Palette built around what both org logos already share (warm orange,
   dark warm brown/grey text) plus BCPL's teal as a secondary accent --
   the logos themselves are never recolored, this just picks colors that
   sit well alongside them. See issue #30.

   Section backgrounds and borders were originally a warm cream/tan tint
   of the orange -- felt too one-note ("peachy"). Retinted as a light
   teal-gray instead, derived from --color-accent, so the teal actually
   reads as a second color in the palette rather than just link text. */

/* The Date facet (hierarchicalMenu) is a stock InstantSearch widget --
   its count comes styled as a blue-tinted pill badge from the CDN theme
   (algolia-min.css), which doesn't match this site's palette at all.
   Overridden to the same plain, muted-text style already used for the
   subject filter's own counts above, so both read consistently.

   Scoped to .search-facets (not just the bare class) so this wins on
   specificity regardless of load order -- the theme's own stylesheet
   is linked from inside the page body (search.html/list.html), after
   this site's own style.css in <head>, so an equal-specificity rule
   here would otherwise lose the cascade to the theme's.

   flex/space-between on .ais-HierarchicalMenu-link didn't actually
   line the count up with the subject filter's, even confirmed applied
   via computed styles -- the real DOM has an extra unstyled <div>
   between <li> and <a> (confirmed via a live DOM dump) that flex
   through an unknown chain of ancestors wasn't reliably resolving.
   Absolute-positioning the count against the <li> itself sidesteps
   that entirely -- <li> is the one element in this chain confirmed to
   span the sidebar's full width.

   `right` is 0.5rem, not 0 -- confirmed via getBoundingClientRect() in
   a real browser that .subject-filter__suggestion's own right padding
   (0.4rem 0.5rem) puts its count 8px left of the sidebar's true edge,
   so right:0 here overshot past where the subject counts actually
   sit. Not a guess this time; measured the exact 8px gap directly. */
