/*
 * Action Text + Trix — editorial override.
 *
 * Replaces the gem's default toolbar styling with Farlist's
 * design tokens. The toolbar markup itself is locked down to
 * italic + link + attach (see app/views/items/_trix_toolbar.html.erb);
 * this file styles those three buttons + the link dialog + the
 * .trix-content render path so attachments and prose look right
 * on the item detail page.
 *
 * Buttons that aren't in our custom toolbar (bold, strike, quote,
 * heading, code, lists, undo/redo, nesting) have their styles
 * intentionally omitted — keeps this file small and prevents
 * accidental "look how bold renders" surface area if the toolbar
 * is ever overridden upstream.
