Redesign homepage into two studios, add version archive, and integrate Elemental Title - #28
This PR addresses two key studio improvements for SEIHouse Font Lab:
Two-Studio Homepage Redesign & Complete Version Archive:
Reorganizes the homepage (index.html) into two clear studio sections:
01 / Regular & Reading Fonts: Highlights SEIHouse Sans 0.42 with an inline compact compare preview and direct links to Reader Lab, Reading Test, and Reference Compare, plus the SEIHouse Noto (Balanced · Refinement 01) companion card.
02 / The Title Engine: Showcases SEIHouse Display 0.1, Living Titles 0.1.3, and Elemental Title 0.1.0 with cut switchers and a balanced 2×2 workspace grid.
Recovers and archives all historical font releases into old/ (0.25, 0.26, 0.35, 0.36, 0.39, 0.40, 0.41, and 6 Display milestones) with cryptographically validated SHA-256 manifests.
Adds a streamlined, compact Version History & Compare subpage (site/versions/index.html) allowing visitors to compare any two releases side-by-side or stacked on demand.
Enforces build-time version synchronization (site/version_inventory.mjs) so homepage version badges never drift behind phase4.json.
Full Migration of Elemental Title (@seihouse/elemental-title 0.1.0) into Font Lab:
Brings the animated ElementalTitle lettering engine into seihouse-font-lab as a dedicated zero-dependency private package (packages/elemental-title/) right beside @seihouse/living-titles.
Packages runtime SVG choreography (Lightning, Water, provisional Poison, plus Fire, Frost, Celestial, Void CSS accents), the page-wide crowd budget coordinator, and official Familiar Signatures (quill/stormwrit and quill/true-north).
Adds the standalone 6-tab Elemental Title Lab (display/elemental/index.html) featuring an interactive SEIHouse Typeface Switcher (Display Edge, Soft, Ink, Wide, SEIHouse Sans 0.42, and SEIHouse Noto).
Builds and gates the release tarball packages/elemental-title/releases/seihouse-elemental-title-0.1.0.tgz and documents step-by-step handoff in docs/APP-INSTALL.md for removing legacy UI files and pointing development to the new package.
Self-Review
Scope reviewed: Homepage layout, version history subpage, font archive manifests, @seihouse/elemental-title package runtime, Elemental Title Lab, website build assets, and distribution CI workflow.
…e Elemental Title
Organize homepage into 01 / Regular & Reading Fonts and 02 / The Title Engine, add compact version history & compare subpage with all 17 preserved Sans versions and 7 Display milestones, and bring @seihouse/elemental-title (0.1.0) and the standalone Elemental Title Lab into seihouse-font-lab.
This pull request adds the Elemental Title React package and interactive lab, plus build, release, and browser-verification workflows. It also adds historical font archiving and version comparison, and reorganizes the homepage around Reading Fonts and the Title Engine.

Discard outdated historical font load results
When someone changes the homepage comparison version or typography controls while an earlier font request is still loading, the earlier request can finish last and overwrite the newer selection. For example, selecting 0.39 and then 0.41, with the 0.39 request finishing last, leaves the selector and label showing 0.41 while the preview renders 0.39. Add a request sequence check before applying asynchronous results, as the version-history page already does in refreshArena().

Addressed in commit 9bc10f0: Added a sequence check (sansUpdateSeq) to updateSansSpecimen so asynchronous font load results from earlier selections are discarded if a newer version or typography setting is selected while loading.

Synchronize the specimen label when updating release versions
After bumping phase4.json, the documented python archive_version.py --sync command updates the marked badges but leaves sans-current-label at 0.42 because that label has no data-sans-version attribute. Consequently, versionInventory() rejects the updated site with “Homepage specimen label ... does not match current Sans version,” blocking the website build even after running its prescribed synchronization command. Include the current specimen label in synchronization so the generated homepage satisfies the build validator.

Addressed in commit 9bc10f0: Updated sync_homepage_version in archive_version.py to synchronize both data-sans-version badges and the Current · SEIHouse Sans specimen label so future runs of python archive_version.py --sync satisfy the site validator automatically.

Forward the public ref through a React 18-compatible component
For consumers using React 18, which the package explicitly supports through its react >=18 peer dependency and README, React does not pass ref as a normal function-component prop. Destructuring it here therefore leaves a supplied object or callback ref unattached, breaking host code that needs to focus, measure, or observe the title element. Use forwardRef to preserve the advertised React 18 compatibility, or explicitly require React 19 instead.
The reason will be displayed to describe this comment to others. Learn more.
Addressed in commit 9bc10f0: Wrapped ElementalTitle in React forwardRef<HTMLElement, ElementalTitleProps> with displayName set, and updated the public declaration in public.d.ts to ForwardRefExoticComponent to ensure full React 18 & 19 ref attachment compatibility.

Resolve the full comparison's base version from the manifest
After the next Sans release is archived and synchronized using the documented release workflow, this link will still pass left=0.42, even though the homepage specimen renders the newly rebuilt current fonts. The version viewer honors that explicit parameter, so clicking “Full archive” silently changes the comparison's base from the current release to archived 0.42. Use manifest.tracks.sans.currentVersion for the base, or omit left so the viewer selects the current version automatically.
The reason will be displayed to describe this comment to others. Learn more.
Addressed in commit 47f92b0: Removed hardcoded left=0.42 parameter and updated the link to dynamically resolve the current base version from manifest.tracks.sans.currentVersion (and fallback to omitting left so the viewer selects the current version automatically).

Restore the overlay when engagement ends.
If a visible water title loses hover during a wave, engaged changes but running stays true. This effect therefore retains the transient frame.

timeout-bounded wait for the reduced-motion state, polling until the relevant
element reports data-running="false" before the following assertion. Preserve
the existing assertion and fail verification if the state does not arrive before
the timeout.
Review comments at @display/verify_elemental_package.mjs:
- Around line 178-180: Update the Windows Python selection used by the
verification command to use an existing configured Python executable when
available and otherwise fall back to python on PATH when the repository-local
virtual environment is absent; preserve the current non-Windows behavior and the
browser-check invocation.
Review comments at @docs/APP-INSTALL.md:
- Line 107: Move the `@seihouse/elemental-title@0.1.0` row out of the October
10, 2026 historical installation record into a proposed-installation section,
keeping it separate from packages already installed. Alternatively, update the
historical record only if the installation has been completed.
- Line 181: Update the documentation around the verify_elemental_package.mjs
command to list the Python Playwright and Chromium installation steps used by CI
before running it, in addition to the existing npm ci prerequisite.
Review comments at @docs/WEBSITE.md:
- Line 127: Update the documented Sans snapshot command to omit the positional
version argument; `--snapshot-sans` takes no argument, and the script reads the
current version from `phase4.json`.
Review comments at @packages/elemental-title/README.md:
- Line 404: Replace both relative links to docs/FAMILIAR-SIGNATURES.md in the
README with absolute repository URLs pointing to the document on the default
branch or a stable tag, so the links work for consumers of the published
package.
Review comments at @packages/elemental-title/src/elemental-title.tsx:
- Line 409: Update the effect in ElementalTitle that depends on children,
effect, stage, tier, and running to restore the still frame when engagement
ends, even if running remains true, so the overlay stays synchronized with
canceled letter animations. Preserve explicit playback for idle titles and apply
the same restoration when a burst ends before its wave.
Review comments at @packages/elemental-title/src/engine/conductor.ts:
- Line 564: Update the non-signature playback path in `play()` to check
`stopped` before calling `begin()`, matching the existing stopped-state guards
for signature playback and `touch()`. After `stop()`, non-signature calls such
as `play("strike")` must not start timelines or emit frames.
Review comments at @README.md:
- Line 13: Update the README instruction for opening index.html to clarify that
the Past versions viewer cannot load its manifest when opened directly from
disk; direct readers to use the server-based preview described below to access
the viewer.
Review comments at @site/home.js:
- Line 76: Update the font-load caching flow around loadedFaces.set(cacheKey,
loader) so a rejected ff.load() removes its cache entry, allowing a later
selection to retry. Evict only the matching loader after rejection, and retain
successful and in-flight loads.
Review comments at @site/versions/versions.js:
- Line 148: Update the `loadedFaces` promise handling so a rejected font load
removes its cache entry, allowing a later selection to retry. Delete the entry
only if it still refers to the rejected promise, and preserve the existing
rejection behavior.
- Around line 424-426: Update init() to handle both a rejected
fetch('../versions.json') request and a non-OK response by showing a visible
error with a retry action; ensure retrying reruns manifest loading and lets the
version selectors populate on success.

Nitpick comments:
Review comments at @display/verify_elemental_browser.py:
- Line 45: Update the signature check in the browser verification flow so it
waits for the expected scene primitives in both the back and front SVG groups
before treating the signature as rendered; do not rely on the data-signature
attribute alone, which may be set before drawing completes.

Prevent an older comparison request from replacing the latest selection.
If a visitor selects version A and then version B before both fonts load, A can finish last. This callback then replaces B’s label and preview with A’s font until another control change. Record a request sequence before the first await. Apply the label, font, note, and error only if that sequence is still current. (raw.githubusercontent.com)

Review comment at @site/home.js around lines 123 - 128:
In the comparison-selection flow around loadManifest and ensureHistoricalFace, increment and capture a request sequence before the first await. Before updating the sans-old-label, oldPreview font, note, or error state, verify that the captured sequence is still current so an older request cannot replace the latest selection.

Addressed in commit 9bc10f0: Added a sequence check (sansUpdateSeq) to updateSansSpecimen before and after font face loading so out-of-order asynchronous responses from earlier selections are discarded.

@SENSEIDUKES Thanks for adding the sequence checks. They protect successful loads, but the catch block in site/home.js does not check seq.
If an older request fails after a newer request succeeds, it can replace the newer note with an error message. Please guard the catch update with seq === sansUpdateSeq. I am not marking the finding as addressed yet.

Remove the version argument from the Sans snapshot command
Following this release procedure fails before preserving the outgoing fonts: python archive_version.py --snapshot-sans 0.42 exits with error: unrecognized arguments: 0.42. The script's verified --help output lists --snapshot-sans without a value, and snapshot_current_sans() reads the version from phase4.json. Remove the trailing 0.42 so the documented command actually creates the archive before the fonts are rebuilt.

Addressed in commit 4d0dfe8: Removed trailing 0.42 argument from python archive_version.py --snapshot-sans in docs/WEBSITE.md to match the flag's store_true definition in archive_version.py.

Do not report a signature after it has stopped.
If onMoment calls stop(), cancelSignature() reports null and clears the completion timer. This line then reports the signature ID, leaving the host with an active signature that will never receive an end notification. Check that showing is still current before reporting the ID.
