Pull request overview

This PR updates the “generate-from-image-design” skill guidance to improve implementation fidelity by making the gotchas checklist more prominent and by adding additional chart/component selection pitfalls to the gotchas reference.

Changes:

• Adds an explicit “read gotchas” blocking step in the mandatory protocol and reinforces gotchas usage during implementation.
• Updates the theme-generation guidance to prefer create_palette(..., output: "css") for Blazor and warns against create_theme (Sass output).
• Expands references/gotchas.md with additional chart fidelity/component-choice guidance (e.g., smooth area “sparklines”, ring/percentage visuals, and chart type selection rules).
