Semiotic v3.8.3

Added

• Narrative examples. Added Earthquakes and Europa Languages examples,
  including deterministic data fixtures and example-gallery previews.

Changed

• Browser/server rendering alignment. Browser, static SVG, and MCP render
  paths now share chart-mode defaults, line and geo styling, legend layout,
  temporal histogram configuration, and specialized network, geo, gauge, and
  custom-chart rendering behavior.
• SSR parity coverage. Replaced the redundant SSR/CSR screenshot matrix
  with semantic markup and targeted geometry assertions, while retaining the
  dedicated cross-browser visual suite.

Fixed

• Docs example route smoke test. The route contract now targets the
  ExamplePageLayout title specifically, and the Earthquakes dashboard uses a
  nested heading level instead of duplicating the page's H1.
