/* Auth-page styles for the chat channel.
 *
 * Loaded ONLY by login.html, forgot-password.html and reset-password.html.
 * The chat surface itself (templates/index.html) does not link this file — it
 * loads tailwind.css plus its own inline <style> block, and that block is where
 * chat/markdown CSS belongs. This file was called styles.css until #2212; the
 * name implied it styled the whole channel, which is how a dead `.message-bubble`
 * rule family and every `.msg-content` rule survived here unnoticed (#2094,
 * #2107). Renamed so the next person doesn't make the same assumption.
