/* CDE3's own minimal stylesheet -- independent build pipeline from the root Preact app and from
   CDE2, but reuses the same palette tokens as apps/cde2-leptos/styles/app.css for visual continuity
   across this repo's three viewer variants (--ink/--paper/--accent/--line/--muted/--dark are the
   same hex values there and in src/styles.css's :root). Layout/structure is CDE3's own -- this DOM
   is simpler than CDE2's (no identity bar, no grouping tables, no draft/save panels), so those rules
   are not ported. */
