{{/* The component kit: one {{define}} per partial of docs/plans/panel-redesign.md
     § Three layers. This is the only file besides layout.html in which an sp-
     component class is written; a page calls a partial and passes the struct
     that components.go declares for it (a page never builds the input with
     dict), and it never rebuilds the markup. The reference for every partial in
     every state is the mockup components page,
     docs/assets/panel-redesign/panel/src/components.html — the markup here is
     that markup, element for element and class for class, and the kit page
     (GET /server/components, kit.html) renders it all from fixtures.

     Go templates have no slots, so a component that wraps the page's own
     content is an open/close pair: box_open … box_close, body_open …
     body_close, record_open … record_close. Between the two the page writes
     Bulma markup (a table in its table-container, a form) or calls another
     partial. */}}
