/* Proofread admin — "galley proof" theme.
 *
 * A copy-editor's marked-up page: warm paper, ink-black type, red strikes for
 * deletions, green for insertions, highlighter yellow for anything still
 * awaiting a decision. Each colour means one thing and only that thing.
 *
 * Type note: the Latin display face is a text serif, but CJK falls back to a
 * *gothic*, not a mincho. Mincho at UI sizes reads loose and mismatched next
 * to Latin serif; gothic is what Japanese and Korean interfaces actually use.
