/*
 * read.gonglogic.com — the feedback box and the forum.
 *
 * A file of its own so library.css stays one system owned in one place; everything
 * here is drawn from that file's TOKENS (--paper, --surface, --ink, --rule, --accent
 * …), so dark mode is already done: the tokens change under
 * `prefers-color-scheme: dark` and nothing here has to.
 *
 * ── THE FORMS
 *
 * The theme styles a bare <form> as a white, bordered, 34rem card with grey inputs —
 * built for gonglogic.com's contact page, with no dark mode, so on a dark library
 * page it would be a white slab. These forms are drawn on the library's surface with
 * its tokens instead. The theme's rules are (0,2,3) at their strongest
 * (`form fieldset .field input[type=text]`); every rule below starts
 * `[data-area="library"] .cm-form` and so outranks them without !important.
