Caveats

• The README states plainly that this is a work in progress with significant refactors planned: naming conventions and armature configuration may change between versions without notice, though old recordings can always be reprocessed with new software.
• MediaPipe output is the only supported input, enforced independently on both the FreeMoCap side and inside the addon's data model.
• The keyboard shortcuts described in register() do not actually bind (class-name mismatch, noted preceding).
• glTF export is present in code but explicitly marked broken and unreachable from the UI.
• A few comments lag the code they annotate (the checkerboard square size, the ground-plane minimum size), so prefer constants over comments when the two disagree.
