/* Rig Doctor (/rig-doctor)
 *
 * Built entirely on the tokens in /tokens.css, which is what makes the page
 * theme-aware for free: the light-theme block in tokens.css redefines every
 * surface, ink, and stroke value, and nothing here hardcodes a colour that
 * would survive that swap. The three verdict colours are the only exception,
 * and they are the token set's own --success / --warn / --danger.
 *
 * Class prefix `rd-` throughout, so this file can never collide with the
 * shared nav, footer, or mobile stylesheets loaded alongside it.
