Window Icons and Cloud Cleanup
Added the missing icon update record and cleaned residual cloud fragments from the Night and Dusk wallpaper plates.
# Window Icons and Cloud Cleanup
This update records a few shipped visual fixes that were not yet grouped into a public site update article.
## Changes
- Added new window titlebar and taskbar icon assets for Knowledge, Videos, Resources, Games, Talk, and About.
- Tuned the section title icon box, scale, and vertical alignment so the icons read more clearly before the title text.
- Cleaned the Night wallpaper `base-clean.png` plate so the moving mid-distance cloud no longer leaves a separated cap behind.
- Checked all four time-of-day wallpapers: Morning and Day did not show the same issue, while a faint Dusk remnant was cleaned at the same time.
- Updated the home CSS cache version to reduce the chance of browsers keeping older icon styles or clean plates.
