 * pages.css: the product, trust, company and guide pages.
 *
 * Linked AFTER style.css, and only by: product-floor, product-voice,
 * product-books, product-intelligence, product-apps, security, about,
 * contact, guides and the two guide-*.html articles. Everything here is a
 * component style.css does not have; nothing here restyles one it does.
 * Colours come from style.css's tokens only, so light and dark follow it.
 *
 * COMPONENTS

 *   ul.hero-facts          small facts under the hero actions
 *   .in-plan               "Included in" row: span.plan-pill (.off when not)
 *   ol.week > li           a week on the desk: .week-day, h3, p, span.screen

 *   .limits                "What it does not do": h2, p, ul.crosses
 *   ul.crosses             drawn crosses, the opposite of ul.ticks
 *   .scope > .scope-col    two columns: what we keep, what stays elsewhere
 *   table.facts            plain data table; cards with td[data-label] at <=860px
 *   .brief                 numbered summary box (security)
