Greptile Summary

Adds prominent documentation notices explaining that Pink inverse-kinematics actions and the Pink-dependent humanoid imitation workflows are supported only on Linux.

• Documents the platform limitation beside the Pink action API.
• Warns users about Linux-only support before the humanoid imitation demonstrations.

Confidence Score: 5/5

The documentation-only PR appears safe to merge.

The added notices accurately describe the platform constraints of the Pink action and all humanoid imitation workflows presented on the affected page.

Isaac Lab Review Bot

This documentation-only change adds Linux platform notices for Pink IK actions and the humanoid imitation-learning workflows. The reviewed edits do not alter runtime behavior or source packages.

• Design and architecture: The notices are placed at relevant discovery points: the MDP Actions API section and the existing important admonition on the humanoid imitation-learning page. No documentation structure or implementation architecture changes.
• API: No public symbols, configuration fields, defaults, exports, or compatibility surfaces change. The API-page admonition clearly identifies the affected Pink inverse-kinematics action and leaves the surrounding automodule directives intact.
• Implementation: The reStructuredText directive syntax and indentation are consistent with the surrounding documentation. One non-blocking wording tradeoff is that the humanoid page describes both its Mimic workflows and Pink IK tasks as Linux-only, which is broader than a Pink-only limitation, but it is scoped to the workflows on that page.

No blocking issues. No inline issue met the actionable-evidence threshold; the assessment above records the review feedback.

Automated review; human maintainers own approval decisions.
