How btn-*/card-* encode their own hover/active behavior.
The original implementation#
Because v1 has no state variants, components bake interaction into their rules — btn-neon glows brighter on hover with no extra class.
Sample#
<button class="btn-neon">hover: brighter glow</button>
<div class="card card-hover">hover: lifts</div>Legacy & migration#
The v1 file is frozen forever. To keep this exact look on the modern engine, follow the migration guide — the whole design system is re-expressed as a Nakshora config.
