/* ── DocMixer ──
 * Scoped styles extracted from the <style> blocks of tools/doc_mixer/{new,edit}
 * and inline style= attributes. Everything is scoped under .dm-shell (the page
 * root, shared by new + edit; streamed broadcast partials and the chat-form /
 * files-panel replacements all render inside it). Bare element selectors
 * (textarea, input[type=submit]) are scoped too. The `spin` keyframe is renamed
 * dm-spin to avoid colliding with lea_raw/personal_agent's global `spin`.
 * JS-toggled display:none states stay inline in the Haml (behavioural, not styling).
