/* One Dark for Forgejo.
 *
 * Imports Forgejo's own dark theme and repaints it, rather than forking a copy
 * of the 15KB file: everything not named below keeps upstream's values and
 * picks up upstream's fixes on the next Forgejo upgrade. The import must stay
 * the first rule in the file — CSS ignores @import after any other rule.
 *
 * The base theme derives 58 of its variables from a --steel-* neutral ramp
 * (900 darkest -> 100 lightest), so replacing the ramp moves nearly the whole
 * UI at once. Only the accent and the syntax colours need naming separately.
