/* Shared styles for the three HarpPilot public pages.
 *
 * These pages are plain hand-written HTML with no build step, so this file is
 * linked directly with <link rel="stylesheet" href="/style.css">. Keeping the
 * styles in one file rather than repeating a <style> block in each page means
 * a change to the look happens in exactly one place.
 *
 * Colors are defined once as CSS custom properties (the `--name` syntax) on
 * :root, then referenced with var(). The prefers-color-scheme media query
 * below re-defines those same properties for readers whose device is set to
 * dark mode, so every rule that uses var() adapts without being written twice.
