/* Tools: shared styles for /tools/ and every tool page under it.
 *
 * Load after styles.css. Site components cover the rest: .eyebrow for step
 * labels, .btn for actions, .glossary-list for definitions, and the global
 * field style for inputs. A tool page is built from:
 *   .tool-page       on <main>; left-aligns card headings
 *   .tool-crumb      "Tools / <name>" link row above the eyebrow
 *   .tool-lede       intro paragraph under the h1
 *   .tool-card       panel for the form, results, and explainers
 *   .tool-row        two-column field grid (one column on phones)
 *   .tool-field      label + input + optional .tool-help
 *   .tool-money      wrap a money input to show a "$" prefix (the picked
 *                    currency's symbol on pages with .tool-currency)
 *   .tool-currency   currency picker above a pure-math tool's form
 *   .tool-percent    wrap a rate input to show a "%" suffix
 *   .tool-modes      pill-style radio group
 *   .tool-hint       live "add X to see your result" message
 *   .tool-results    result panel; set data-tone="caution|good|great"
 *   .tool-band       big italic verdict word, coloured by data-tone
 *   .tool-gauge      three-zone meter with a moving .tool-marker
 *   .tool-stats      row of four .tool-stat figures
 *   .tool-callout    boxed aside inside results
 *   .tool-next       pill links to assessments and guides
 *   .tool-formula    centred formula callout
 *   .tool-funnel     "money is one dimension" card leading to the Wealth Score
 *   .tools-finder    search box + dimension chips on /tools/ (js/tools-finder.js)
 * Tool-specific pieces stay in the page's own <style> block.
