/*
 * Page-wide styles, loaded on every page after Bootstrap and before the section files
 * (sections/<section-class>.css). Only rules that aren't about one kind of section belong here.
 *
 * Contents: page layout, Bootstrap grid adjustments, typography and the type scale, links, buttons,
 * images, focus, small utilities and effects. Media queries sit right after the rules they adjust.
 *
 * Conventions for every site stylesheet:
 * - A section file holds the section's own rules, then its variants, then its media queries.
 * - Variants are modifier classes (class="feature-row feature-row--image-right"), styled as
 *   `.feature-row:where(.feature-row--image-right)`. :where() adds no specificity, so a variant rule
 *   weighs exactly what the plain class does and wins only by coming later: keep variants below.
 * - Change the rule that already styles something rather than adding a later override.
