A MishkaGervaz custom table template: the Design tokens list inside the page builder's Studio.

It owns the whole of the list and nothing around it. The tab's heading, the export-format tabs and the export block below stay in MishkaCmsCoreWeb.Live.Admin.Builder.Panels — they are not a table.

features/0 is empty on purpose: the Studio is a 480px sheet, and Gervaz's own filter bar, selection checkboxes and pagination footer would each be a control the design does not have. The category chips ARE Gervaz filters, but drawn here in the sheet's own idiom and pushed as the table's own filter event; the load-more button is drawn here too, for the same reason.

The rows come from @state.loaded_records rather than from the stream, because the design groups them under category headings and a stream is one flat container that appends — it cannot express a heading. That is what keep_loaded_records true on the resource is for: Gervaz keeps every loaded page, so its own load_more event works for a grouped list exactly as it does for a flat one.

The category chips' counts arrive in path_params already computed, because they count the WHOLE token set and the whole set is a 33 ms parse of the site's stylesheets — a cost worth paying once per revision in the LiveView, not once per render here.

The one style attribute left, and why

A category heading's dot is one of seven colours Panels.grouped_tokens/2 hands over, so dot_class/1 spells each out and the attribute is gone — CSP has no nonce for an attribute, so style-src-attr can only be closed by there being none.

The plain swatch beside a token cannot follow. Its colour is @token.value, a declaration read out of whatever stylesheet the site's theme happens to be — any hex, oklch(…), a gradient, a var(--x) — so there is no finite set to write out and none to declare with @source inline either. It stays an attribute until the swatch can be given a rule of its own in a nonced <style>, which needs a nonce this template is not handed.
