/* ════════════════════════════════════════════════════════════════
   Subscribe Link Generator — bespoke night hero + bookend + mobile fixes.
   Layout only; composes the shared night kit (components/night.css).
   Loaded after tools.css (which carries all the slg-* tool internals).
   The tool's #1 traffic page; also fixes a pre-existing 375px overflow
   (a wide .button--lg in the bottom CTA + long <code> blocks).
