Walkthrough

This PR adds 90 lines of CSS styling to the VitePress documentation theme, targeting multiple UI components including feedback forms, attachment previews, history menus, form uploads, and custom-block layouts. All changes are pure styling adjustments with no functional code modifications.

Changes

Component-Wide Styling Adjustments

Layer / File(s)	Summary
Feedback component styling .vitepress/theme/style.css	Feedback source pill links styled with color and weight, with underline appearing on hover. Feedback action dropdown lists have default list-style removed and padding/margins normalized.
Attachment and history menu styling .vitepress/theme/style.css	Attachment file preview images have extra margins removed; download action links use brand color and weight with consistent underline behavior. History menu lists have bullets removed and spacing normalized with compact margins between items.
Form upload and custom-block layout fixes .vitepress/theme/style.css	MCP form upload/picker component images render as block elements without extra margins. Tiny-robot route custom-block elements convert to a two-column CSS grid, with child elements and list content constrained to the second column and the pseudo-element ::before positioned in the first column.

Poem

🐰 The styles align with grace so fine,
Each component now will truly shine!
Pills and lists and grids arranged,
The layout dance is now exchanged.
A rabbit's work makes pages bright! 🌟
