/* Crux Assessor — capture-only intake styling.
   Brand tokens, header/nav, footer, buttons, chips, and callouts mirror the
   crux-assessment tool (assets ported from crux-works.com) so the two products
   read as one. Visual only — no scoring, no band colors used as a rating.
   Score/band palette (rust->gold->moss->slate) is intentionally NOT wired to any
   answer value here; this tool never displays a score. */
