/*  Review CMS - interface styles.
 *
 *  One stylesheet, no framework and no build step, so the office PC can serve
 *  it straight off disk. Colours are CSS variables in one place at the top;
 *  the dark theme redefines those variables and nothing else, which is why
 *  every component below is written against the tokens rather than a hex code.
