Closes #951

Description

This PR implements subscript notation for displaying very small amounts (e.g., 0.0₅1 instead of 0.000001) across the Mobile Wallet, Desktop Wallet, and Explorer. This improves readability for token amounts with many leading zeros.

Changes

  • Implemented standard subscript formatting utilities in the shared package.
  • Updated [formatAmountForDisplay] to support optional subscript formatting.
  • Enabled subscript notation in Desktop Wallet, Mobile Wallet, and Explorer Amount components.
  • Added specific styling for subscript characters (secondary font color) in Desktop and Explorer.
  • Added comprehensive unit tests for the new formatting logic.

Verification

  • Unit tests passed (pnpm test packages/shared)
  • Linting and Typechecking passed (pnpm check)
  • Visual verification in Desktop, Mobile, and Explorer

Thanks for the reply!

One issue I found when testing the apps is that the color fo the subscript doesn't follow the color of the rest of the amount text. The following screenshot is an example of the transactions list amounts in the desktop wallet. Since it's an incoming transaction, the wallet changes the color of the amount to green, but the subscript amount remains gray. Could you please have a look?

PS: On mobile wallet it seems that it works correctly
