Pull request overview

This PR introduces a base text size scale to the design token system and migrates functional typography tokens from hardcoded pixel values to references to this new scale.

Changes:

  • Added a new base.text.size scale with six size tokens (xs through 2xl) using rem units
  • Replaced hardcoded pixel values in functional typography tokens with references to the base size scale
  • Updated the dimension value schema regex to support decimal rem/px values required by the new scale

The regex pattern has been updated to support decimal values like '0.75rem' and '2.5rem', which is necessary for the new text size scale tokens. However, there are no test cases in the dimensionValueSchema.test.ts file that verify decimal rem/px values work correctly. Consider adding test cases such as dimensionValue.safeParse('0.75rem') and dimensionValue.safeParse('2.5px') to ensure the regex change works as intended.
