Add the Vessel family: vessel-react, vessel-light fingerprint, steering-eval harness (#207)

* Add vendored vessel-react fingerprint: taste-floor nodes, materials wired to component sets, baseline hygiene checks

* Rename packages/vessel to packages/vessel-react; workspace fingerprint id follows

* Add vessel-light: Vessel's design language as a portable .ghost fingerprint for raw HTML/CSS agents

* Add steering-eval: portable before/after evaluation harness for Ghost fingerprints; wire vessel-light demo as first consumer

* Fix pilot findings: agent-browser set-viewport invocation, skip empty cells, brandTokens/pulledWords from tape

* Run the full steering-eval matrix on vessel-light: 45 generations + dump-growth, screenshots, metrics, report

* Park eval run artifacts on vessel-eval-artifacts branch; ignore demo/out on mainline

* steering-eval: emit WebP screenshots (shoot to PNG, convert via cwebp, embed webp in report)

* vessel-light: fork-axis re-authoring — grammar/signature/register + median floor (#208)

* materials: tokens audit — radius roles, hoist grammar-enumerated values

* corpus: fork-axis re-author — grammar/signature/register/anti-goal

* checks: relationship/value split — density.md retired, median-tells gains demoted rules, frequency thresholds, model-named tells

* materials: regenerate refs — annotated, closed-set complete

* docs: vessel-light README — fork-axis structure and ref-annotation curation

* ghost init: naked skeleton default — grammar, unanswered dials, median floor (#209)

* template: naked skeleton replaces steering default

* checks: median-tells scaffold — live check pairing with anti-goal.median, deterministic floor, model tells

* skill: migrate Morrow teaching shapes to authoring-scenarios

* docs: skeleton starter in getting-started + cli-reference; minor changeset

* ghost init --body: packed payloads + vessel-light body install (#210)

* init: packed-payload mechanism — dist payloads, byte-capable template seam

* template: skeleton rides packed files

* init: --body vessel-light — install the full inhabited package

* checks: packed-artifact body probes — fonts and checks survive pack

* docs: body install in getting-started + cli-reference; minor changeset

* skill: adapting-a-starter — the seven-step starter transplant recipe (#211)

* skill: adapting-a-starter recipe — the seven-step transplant procedure

* review: resolve package-relative material locators when matching diff paths (#212)

* review: resolve package-relative material locators when matching diff paths

* demo: drop stale parked-branch reference from eval artifacts gitignore

* median: one authored home — model truth stamped at init, prunable by contract (#213)

* corpus: audit backports, check cross-wiring, terminology sweeps

* median: one authored home — headings contract, payload check, all templates stamp the floor

* vessel-light: re-derive median onto the headings contract; docs get the ownership reframe

* build: root build and packed-package check produce the full ghost artifact

Root pnpm build only ran tsc, so dist/init-payloads and dist/skill-bundle
were missing in CI: the vessel-light body test failed and check-packed-package
packed a tarball without payloads. Root build now chains the package-level
build; check:packed-package builds its own complete artifact since the lint
job never runs pnpm build.

+The skill bundle gains the `adapting-a-starter` recipe: the seven-step transplant procedure for turning an installed starter — a body like vessel-light or the naked skeleton — into your own brand's fingerprint, plus guidance for consuming an unadapted starter honestly.

+`ghost init` gains `--body vessel-light`: install a full inhabited fingerprint package — answered signature dials, a materials tree with tokens and embedded fonts, annotated reference compositions, and its own checks. Init template payloads now ship as packed files in dist, so bodies can carry binary materials.

+The median floor gets one authored home: `anti-goal.median` rules become markdown headings with per-rule check references, so `ghost validate` warns on every flag orphaned by pruning. All init templates (`skeleton`, `minimal`, `composition`) now stamp the median node; `ghost checks init` copies the paired check from the packaged payload and skips it when the node is absent.

 Surfaces in this repo carry their own fingerprints: `apps/docs/.ghost` and

+`packages/vessel-react/.ghost`. If you touch a surface, `ghost gather` from its
 fingerprint before you build, and expect review against it. This is where
 you experience Ghost as a user — treat friction you hit here as a bug worth
 reporting.
