/* AAC app census (/aac-app-prices/). Loaded after site.css on that page only; uses its tokens, so light and dark
   follow the rest of the site. Charts: tools/aac_census/charts.py (inline SVG, percentage x positions).
   Series colors, validated with the dataviz validator against the chart surface in each mode (2026-10-30):
   pay once = teal, a year of subscription = orange; light #007FA8/#EB6834 on #FFFFFF, dark #2F96BA/#D95926 on
   #0E1C21: lightness, chroma, CVD (17.3 / 20.4) and contrast all pass. Text never wears a series color.
   Unit chart (an ordinal pair of one hue: "one of the ten most-rated" darker in light mode, lighter in dark):
   light #7DBAD0/#007FA8, dark #1F5C6E/#8AD6EC, validated with --ordinal (light end >= 2:1 on the surface). */
