   Cloud Carma — website styles

   ALL colours, fonts, and spacing live in this one block. Change a value
   here and the whole site follows. Nothing below this block should contain
   a raw colour, font name, or spacing number — it all points back here.

   Where each value comes from:
   - "Design" = Cara's own site design, the Claude artifact "Cloud Carma Beauty"
     (https://claude.ai/artifact/7AmRzSJW62qy2sZ9ce3bL2). That design is the
     source for everything below; there is still no dedicated Visual Identity
     note in the vault.
   - "Vault" = the vault note Marketing & Brand/Inspiration/Cloud Carma
     Homepage and Studio.md, which documents the same palette in hex.
