Unified Theme Hardening (Visuals & Defaults)

[nicolethoen]

Summary: Refine the Unified Theme to align with final design specifications and set new defaults. This includes specific token updates (colors, border radii) and establishing the "out-of-the-box" experience (Glass and Brand Icons on by default).

Scope / Child Issues:

• Token Updates
  • Color: Replace PatternFly Blue with Red Hat Red accent tokens.
  • Shape: Increase border-radii (pill shapes) for drawers, buttons, and menu toggles, nav items, tab items, (+ more that design identifies)
• update components to use branded icons
• Add theme switcher to the docs site for testing [done]
