Walkthrough

Adds targeted CSS rules to the VitePress theme: feedback source “pill” link and dropdown padding tweaks, attachment download link styling, preview image and list normalization under _tiny-robot_, and a _tiny-robot_-scoped two-column grid layout for .custom-block.

Changes

Documentation Theme Styling

Layer / File(s)	Summary
Feedback pill, dropdown, and attachment link styling .vitepress/theme/style.css	Styles feedback “source pill” links (color/font-weight/hover underline), adjusts feedback action-group dropdown padding, and sets attachment download action links to use brand link color with consistent underline suppression.
tiny-robot preview image and list normalization .vitepress/theme/style.css	For _tiny-robot_ previews, forces images to display: block with zero margin; removes default ul/ol list styling and normalizes li line-height and spacing.
tiny-robot .custom-block two-column grid layout .vitepress/theme/style.css	Implements a 2-column CSS grid for .custom-block under _tiny-robot_, moves child content into column 2, resets list margins/padding inside the block, and places the .custom-block::before icon in column 1.

Poem

A rabbit hops through style and rule,
Pill links gleam and previews cool,
Downloads dressed in brand-new hue,
Tiny robot grids line two-by-two,

.vitepress/theme/style.css (1)

860-863: 💤 Low value

Redundant hover state properties.

The hover state re-declares text-decoration: none and border-bottom: none, but both properties are already set to none in the base state (lines 856-857). These declarations have no effect and can be removed.

♻️ Simplify hover state

 .vp-doc[class*="_components_attachments"] .tr-file-card a.tr-file-card__action-btn--download:hover {
-    text-decoration: none;
-    border-bottom: none;
 }

If no hover-specific styling is needed, the entire hover rule can be removed.
