Description

Close the passive delivery records after the existing atomic Dark snapshot was merged through PR #51. Record the byte- and mode-preserving adoption in the original checkout, reconcile the obsolete historical checklist, and retain the separately blocked screenshot report.

Type of Change

• docs: documentation

Verification

• PR feat(theme): activate dark snapshots atomically #51: all eight exact-head hosted checks passed before merge e9b73fd.
• Original adoption: all 32 working-file byte/mode snapshots preserved; all 30 runtime paths became clean.
• The isolated added-file/index-adoption probe passed before the real operation.
• Native assessment: passive; parent structural readback is complete. No new runtime tests are applicable to these two documentation-only changes.
• Normal commit hooks must pass before this PR is created. This PR must independently pass its configured hosted checks before merge.

Scope and remaining input

Only odd/tasks/readme-main-delivery.md and odd/tasks/publish-dark-snapshot.md change. No runtime logic, activation, dependencies, provider settings, or Git history is rewritten. The newly reported screenshot path is unavailable; no diagnosis or visual correction is claimed without the artifact.

Risk: none (passive delivery evidence only).

Chain Context

This passive closing slice follows merged PR #51 and targets main. It does not recreate the already integrated ML4W/Bat/README delivery or split the atomic mode snapshot.
