RC6.1.21co - Sticky Preview Scroll-Container Authority
- Fixes mini preview not following scroll from Gradient Studio onward.
- Root cause: Gradient and later Studios place the sticky preview inside .windowbg.themelab_workspace_window; active/generated themes can assign overflow to .windowbg, turning it into a non-scrolling sticky container.
- Theme Lab now explicitly owns workspace overflow/contain and sticky positioning.
- Preserves RC6.1.21cn gradient and preview-state authority fixes.

RC6.1.21cm - Membergroup Requests Structural GenericList Fix
- Wraps group_request_list in an owned Theme Lab body during publish.
- Connects the Membergroup Requests header, table, and action area without relying on fragile sibling selectors.

RC6.1.21bk - Registration Header Separation
- Restores a standalone rounded Registration Form title with a 12px gap before Required Information.
- Keeps Required Information, Additional Information, and Verification as seamless title/body components.

RC6.1.21bh - Dark Surface Completion + Board Row Polish
- Joined Board Index rows into soft collections using Theme Lab border/radius values.
- Removed stock Curve2 white gradients and bright square row boxes from .up_contain.
- Added late dark-surface ownership for table_grid and Package Manager install/uninstall action rows.
- Made Theme Lab Publish package preview and pipeline cards honor generated theme surface/text/border variables.

RC6.1.21bh - Board Row Compile Target Fix
- Corrected published Board Index row-color selectors to target SMF 2.1 `.up_contain` board rows.
- Normal Board Row Background now compiles onto every real board row.
- Alternate Row Background now compiles onto even board rows when Alternating Rows is On.
- Preserves the Palette link-state and explicit alternate-row controls introduced in RC6.1.21be.
