Fixes & Engineering
Reduce the extension ZIP from 112.53 MB to 7.87 MB, about 93%, by distributing pre-baked runtime artwork.
Preserve all original artwork and calibration files in the repository. Keep current rendered pixels, building placement and contribution counts unchanged in the verified Chrome paths.
Prepare complete English and Simplified Chinese screenshot sets; the global set matches the English set.
Deployment Notes
The maintainer confirmed submission of version 0.1.1 to the Chrome Web Store on November 4, 2026. It is under review; the store update has not been confirmed live.
The previously confirmed Chrome Web Store version is 0.1.0. Store review and this GitHub release are tracked separately.
No new permissions, remote asset service, account, token, backend or telemetry. Existing local language preferences and contribution caches are unchanged.
The original 0.1.0 ZIP remains preserved. Code and artwork licensing remain separate under LICENSE, ASSETS.md and THIRD_PARTY_NOTICES.md.
Verification
Tests: 57 runtime images and nine complete 1/3/20-year scene comparisons match the prior rendering pipeline pixel-for-pixel in local Chrome. Real GitHub loading, zoom/expand, graph switching and cancel/retry paths passed.
Builds: TypeScript checks, release build, ZIP CRC, inventory, resource references, versions, permissions and notices passed for the 77-file 0.1.1 package.
Edge, cross-platform pixel equivalence, full assistive-technology coverage and long-term memory/GPU/power budgets were not independently verified.
