GridPilot v1.0.0-preview.4

Recursive grid now previews placement over your visible desktop and supports multi-cell selection.

• Thin grid lines and a restrained orange highlight show live proposed bounds while your desktop and windows remain visible.
• Click places one cell. Hold left-click and drag in either direction to select current leaves, including unequal nested cells; release places their axis-aligned bounding box. Escape cancels before commit.
• A divides every eligible leaf one level. Configure or clear this picker-only shortcut under Settings > General. Middle-click undoes a bulk division as one step. Depth and window minimum limits still apply.
• Fixed false minimum blocking caused by treating current/restored size as a minimum after a failed query, clamping app overrides to larger system defaults, and retaining invisible borders in standard maximized-window minimums. Unknown/default limits are labeled estimates. App refusals retain exact placement verification and recovery.
• Original HWND/process capture, physical work-area/DPI geometry, right-click subdivision and placement Undo remain intact.

Local validation: Release build with warnings as errors, portable packaging, independent source review and real desktop UI screenshots. Local test suites and native automated assertion harnesses were skipped at the owner's explicit request. Prior assertion totals do not validate this release. Existing GitHub build/core-check and release workflows remain unchanged and their results are recorded independently. Mixed-DPI/multi-monitor, custom chrome, protected/elevated/RDP apps and application-specific minimum behavior remain manual limits.
