/* alienmachine-ui content shell (blog / articles / archive / search / generic pages).
 *
 * These pages render markdown-produced HTML (not amui-compiled sections), so this stylesheet gives
 * the page chrome + prose a coherent, theme-reactive skin built ENTIRELY on daisyUI's --color-*
 * tokens. Because every color resolves from the active [data-theme], switching themes (incl. the
 * reader override) restyles the whole content page with no recompile — exactly like the amui-compiled
 * docs/home pages. Scoped to .amui-content-shell so it never touches amui-compiled layouts.
