Expose 846 options from 15 pinned PS5 core catalogs before first use,
with categories, descriptions, exact choices, saved-value preservation,
and Advanced mode. Include installed cores without saved profiles and
preserve first-use PPSSPP/Dolphin edits through their profile migration.
Bind dynamic runtime options to the catalog and core binary revision.
Validation: all five tools/verify.sh gates pass (96 tests), all 15 core
browser checks pass, and the deployed native menu-only run exposes all
846 catalog keys with matching JSON, build identity and normal return.
Restore original settings and stop the temporary helper after testing.

Serve the approved purple layout with local assets, streamed content transfers, release notes and next-launch settings. Keep the service within the title lifetime and preserve explicit launch overrides.

Design review and normal Impeccable completion passed in a hash-verified identical-source snapshot because the original-root fingerprint scanner failed; records remain in build/verification. No game performance soak claimed.
