/*
 * AskDimitri member tools: shared styles for /dashboard/tools/ (the hub and every tool page).
 * Colours and fonts come from /css/tokens.css and /css/fonts.css; link both first.
 * Mobile first: one column by default, wider layouts from 720px.
 *
 * Components: .tool-header, .tool-title, .allowance, .ai-note, .card, forms and buttons,
 * .notice, .steps (progress), .light (traffic lights), .status (reference results), .flag,
 * .result-list, .copy-block, .tool-cards (the hub), .print-only and print rules.
 * Meaning is never carried by colour alone: every light and status has a text label, and the
 * lights also differ in shape (circle, triangle, square).
