Overview theme card: starter identity (option B)

[georgeolaru]

Part of the Pixelgrade Design hub label + Overview redesign (design doc: docs/plans/2026-06-17-pixelgrade-design-hub-overview.md, §3). Depends on #55.

Modernise the demoted theme card to show the client's starter identity instead of the on-disk engine theme.

• Title: clean starter name (e.g. "Rosa" / main_product_title).
• Secondary: quiet "on Anima" (engine) + block/classic badge + version.
• Thumbnail: the starter image (net-new vs Care).
• Fallback: when no starter identity (free/unlicensed, disconnected, offline) → fall back to the real theme (Anima + its own screenshot). Never show a broken image or empty title.

⚠️ Architectural fork — RESOLVE BEFORE BUILDING

The starter identity (main_product_title + starter image URL) needs a free-path data source. In Care both came from the license; in the Assistant/Plus split the free Overview must render without Plus, so the host pixelgrade.com account is arguably the more natural owner — but the 8-key account identity contract carries no product title/image today, and extending it touches the shared Assistant/Plus boundary. Trace the available data, then confirm the source/accessor with George before wiring. Keep Overview.js presentational; add the starter identity to the pixassist_get_overview_data() payload.

Done when

Source confirmed + wired; card shows starter identity when available and falls back to Anima otherwise; pin tests green; bundle rebuilt; verified live (licensed → starter, otherwise → Anima).

Decision (2026-06-17): deferred — carried as an open issue.

Traced the data: the starter identity (main_product_title + starter image) has no free-path source in Assistant. The title lives only in the license (get_license_mod_entry('main_product_title'), now Plus's commercial domain — empty on a free site); the starter image is not stored anywhere in Assistant; and the 8-key host account is identity-only. The values live entirely in Pixelgrade Plus (src/Products/CustomerProductsRepository.php, src/License/LicenseState.php, and src/StarterSites/StarterSiteCatalog.php, which already carries starter screenshots).

So on a free/Plus-less site there is legitimately no starter identity → the Anima fallback is the correct state, and that fallback is already live (the demoted current-theme card shipped in #55). Option B's "degrade to the real theme" path is therefore satisfied today.

Recommended future approach (when picked up): a host-owned seam — pixassist_get_overview_starter_identity() accessor + a pixassist_overview_starter_identity filter that Plus populates (title from License/CustomerProducts, image from StarterSiteCatalog), defaulting to empty → Anima fallback. This matches the existing shared-contract pattern (pixelgrade_assistant_plus_status, pixelgrade/admin_hub/tabs, pixelgrade/admin_hub/starters) and needs the usual lockstep: contract doc + a Plus consumer PR + pin tests both repos. Not the 8-key identity account contract.

Out of scope for the current Pixelgrade Design redesign delivery; #57 (i18n + final build) no longer depends on this.
