   Prose — CoachOS Design System · SINGLE SOURCE
   ──────────────────────────────────────────────────────────────────────
   THE one prose rule set, consumed by every formatted-prose surface so they
   can never diverge (WYSIWYG by construction, DRY):
     • .rich-text                      — coach Content display (Element)
     • .ds-lexxy-editor .lexxy-editor__content — the Lexxy authoring body
     • .participation-text-answers__rich       — member RICH answer render
   Pre-soul typography: sans/inherit body, no reading measure cap. The Study
   voice is NOT routed through html[data-soul] — it lives only on participation
   Content elements that opt in via .rich-text--reading (step.css).

   Replaces the duplicated prose blocks previously hand-synced in
   components/rich-text.css and components/lexxy.css — those files now
   @import or rely on this (delete their duplicated heading/list/quote/
   table/code rules). Email-inliner + PDF (report.css) stay co-dependents,
   kept in lockstep with this file.

   Load order: after base/souls/*.css, before page styles.
