Schemas

Pressundo schemas are plain arrays. Field helpers return field arrays; pu_section() groups fields; options pages and metaboxes consume sections. This keeps configuration portable and avoids proprietary builder objects.

$field = pu_text('headline', ['label' => 'Headline']);
$section = pu_section('content', [$field], ['title' => 'Content']);

A schema describes UI and validation. Stored values remain independent of the UI skin.
