/* --- SDUI widget design tokens -------------------------------------------
 * pkg/ui_htmx serves the widget stylesheet (assets/nhc-form-widgets.css, the
 * verbatim shared rules for the date/time picker, its calendar grid and the
 * rich text editor) in the NHC design-system token vocabulary. The portal
 * theme speaks --portal-*, so it declares that vocabulary for the widgets
 * here rather than forking the shared stylesheet. Same mapping this file's
 * header documents for the hand-ported rules below, so both halves of the
 * form surface read the same colours.
 * Declared on the widgets (not on :root) so a portal page that also embeds a
 * design-system surface does not have its global tokens shadowed. */
