No Inline Style Rules

Instruction files must not use agent-specific rendering directives like inline styles or scripts.

Antipatterns

• Adding <style> blocks to control how an instruction file renders in a preview tool -- the check flags <style tags as forbidden content.
• Using style="color:red" on an HTML element to highlight a warning -- the check detects inline style= attributes.
• Embedding <script> tags for interactive examples -- the check flags <script as a rendering directive that does not belong in instruction files.
• Adding class="highlight" attributes to HTML elements -- the check also flags class= attributes as rendering directives.
