 # Heading 1 — The Necropolis Reads
 
 This is a long paragraph designed to test measure and vertical rhythm at roughly sixty to seventy-five characters per line. Rotkeeper's reading-first themes must keep line length constrained, spacing even, and contrast legible whether the palette is phosphor green on black, macOS Terminal graphite, or PowerShell blue. The same body will render through every theme in the gallery, and the fixture lives beside `oliver-smoke` under `bones/scripts/tests/fixtures/theme-eval/`.
 
-A second paragraph with **strong emphasis**, *emphasis*, `inline code`, and a [relative link](my-first-page.md) plus an [external link](https://example.com) ensures link rewriting, escaping, and inline parsing remain correct deposit. Escapable characters: `& < > " '` must be escaped in titles and descriptions but not in `$body$`.

-Fifth-level heading for measure and hierarchy checks: it must keep the same legibility bar as every other level, with no unexpected size collapse on any theme.
+A fifth-level heading exercises the descending heading scale that docs-style outlines produce. Most themes stop styling at h4; this level must still render legibly from the browser default rather than collapsing into body text.

+The sixth level is the deepest CommonMark heading. It must remain distinguishable from body copy and from h5, even where a theme deliberately mutes it.

This paragraph must remain legible at 768px and 375px widths, with table and code fences not exploding the layout. The `theme-brutal` palette `mac` here should still pass the contrast audit planned in #258.

 Horizontal rule is open — the divider primitive will be visible below if templates use a shared divider style. Expect minimal drift between `theme-spooky-dark.html` and `theme-textpattern.html` after the skeleton standardization (#245).

 ## Frontmatter Contract Check
 
-This fixture exercises the seven tokens from `oliver-contract.md` §template dialect (`title`, `description`, `author`, `date`, `palette`, `$assets_root$`, `$body$`) plus `$if$/$endif$` gating. Rendering through `theme-kawaii.html` (subset tokens) and `theme-brutal.html` (full set) should both succeed; unknown `$tokens$` must pass through verbatim.
+This fixture exercises the template dialect from `oliver-contract.md`: the typed metadata tokens (`title`, `description`, `author`, `date`, `palette`), the v2 extended tokens (`version`, `subtitle`, `tags`, `asset_meta`), the raw `$assets_root$`/`$body$` pair, and `$if$/$endif$` gating. Rendering through `theme-kawaii.html` (subset tokens) and `theme-brutal.html` (full set) should both succeed; unknown `$tokens$` must pass through verbatim.

+- `version` is adapter-injected from `bones/config/version` — footer stamps (`v$version$`) must read the current release, not frontmatter.
+- `tags` joins as `fixture, theme-eval, template-contract-v2` — themes with a `$if(tags)$` footer slot show it; others omit cleanly.
+- `asset_meta` serializes as `eval.md — 0.7.0-fixture — Fixture Harness — Rotkeeper — All Rights Reserved` (name, version, author, project, license joined with ` — `, `tracked` never rendered). The `-fixture` suffix distinguishes page provenance from the engine's `v$version$` stamp by default.
+- The v3 generic hook (#269): any extra scalar frontmatter key is interpolatable as `$field$`. This fixture carries `page_type: tomb-not-found`, so rendering through `theme-necropolis.html` self-exercises the hook — expect `data-page-type="tomb-not-found"` on `<body>` (the 404 scene CSS still keys on the literal `404`, which stays owned by `home/content/404.md`).
+- Site navigation (#244) renders through the literal `<site-nav></site-nav>` placeholder, not an escaped token — themes without the slot are unaffected.
+- `$warnings$` is reserved with no adapter feed yet; it substitutes empty.
 
 - Keep CommonMark-safe: no task lists (`- [ ]`) that would render literally, no footnotes.
 - Raw HTML is not present here — XHTML fail-closed (`error.RawHtmlNotXmlWellFormed`) is not exercised, keeping HTML vs XHTML bytes identical for this page.
