/* nhc-form-widgets.css — the one stylesheet for the widgets that
 * pkg/ui_htmx/templates/form_surface.tmpl renders, that
 * assets/nhc-form-enhancements.js drives and that the React client's
 * UniversalDatePicker, UniversalDateRangePicker and RichTextEditor render:
 * the local date/time picker, its calendar grid and the rich text editor.
 *
 * This file is the single owner of those rules for both renderers. The
 * widget markup, the widget JS and the widget CSS are one contract, so they
 * live together under pkg/ui_htmx/assets: Go embeds this file and serves it
 * at FormWidgetStylesheetPath, and the React components import it by
 * relative path, exactly as they already import the widget JS from
 * clients/ui-react/src/lib/datetime-core.ts. There is no second copy under
 * clients/ui-react/src to keep in step.
 *
 * It is served as one file, so a relative @import would resolve against the
 * serving path and 404: the rules that used to live in richtext-source-mode,
 * richtext-white-surface and richtext-fullscreen are inlined below.
 *
 * Design tokens: this file uses the shared NHC design-system token names
 * (--border, --ring, --text-high/med/low, --bg-level-1/2, --ds-z-*). A host
 * whose stylesheet uses different names declares them for these widgets;
 * the portal theme does that in pkg/cmsportal/theme/assets/portal-account.css.
