   Ramekin v4 shell components — Wave A

   Additive component classes for the v4 redesign. Nothing in this file
   restyles an existing page — every selector here is a brand-new `.v4-*`
   class with no collisions against existing class names (checked via
   grep before this file was written). Later design waves consume these
   classes directly instead of writing one-off card/button/chip CSS per
   page.

   Tokens only: every color, radius, and shadow below references a
   design-tokens.css custom property. The three tokens this file needed
   that didn't already exist (--chip-success-border, --chip-success-text,
   --chip-attention-border) were added to design-tokens.css itself, not
   here, so the token layer stays the single source of truth.
