/**
 * An assistant's reply, rendered as the markdown it is written in.
 *
 * The parsing is the library's. Markdown is somebody else's specification, and a hand-written
 * subset of one disagrees with it at the edges -- which is where the bug reports come from, one
 * case at a time. This file's whole job is the mapping onto the app's palette.
 *
 * Colours come from the theme rather than from the renderer's defaults, so code, links and rules
 * are the same Catppuccin values the rest of the app uses. Nothing here picks a colour of its own.
