/* Social Security claiming-age calculator. Loaded after site.css (same paper / ink palette, Inter); not with calc.css
   (the 401(k) calculator's). Only these two pages load it, so, like calc.css, its class names are not scoped; the shared
   header and footer use none of them. No inline styles: the page is served under style-src 'self'.
   The three claiming ages have their own colours, validated as a set on the light chart surface (all pairs). */
