 * Palette note: --color-accent is pulled directly from the real logo
 * (images/mainlogo.png) — sampled pixel colors: icon mark #5EA9DD,
 * "root" wordmark #2A2A28, "Server Technologies" tagline #3B5998. The
 * tagline blue is used as --color-accent (better contrast on white
 * than the lighter icon blue, which is kept as --color-accent-light
 * for decorative use); --color-ink stays close to the wordmark's near
 * -black rather than a colder pure black.
