 * popup.css — the email sign-up pop-up (Phase 6, D; template-parts/signup-popup.php,

 * the sanctioned @media breakpoints (each commented with its --bp-* token name).
 * Enqueued wherever the pop-up renders (spalux_show_popup() in functions.php).
 *
 * A native <dialog>: surface panel on a hairline, --radius-none corners, the
 * shared .capture capsule inside. Full width less the --container-pad gutters on
 * phones; --container-narrow wide from --bp-md, where an existing lifestyle photo
 * joins as a media column. Entrance: --duration-base + --ease-out, none under
 * reduced motion.
