/**
 * SUEWS Subpage Styles
 *
 * Shared layout for secondary pages: /team/, /funding/, /dependencies/,
 * /management/. Keeps the landing page's visual system (palette, fonts,
 * theme) but strips the heavy hero treatment — subpages carry only a
 * single subtle contour ring as a signature echo.
 *
 * Requires tokens.css and base.css to be loaded first.
