<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Low Risk**
> Low risk: primarily copy/translation key updates plus minor UI
tooltip/toast rendering changes (adds a terms link and an extra
success-toast description) with no changes to conversion logic or data
handling.
> 
> **Overview**
> Updates mUSD conversion user-facing messaging to consistently describe
the incentive as an *annualized bonus* and to communicate that the bonus
becomes claimable within about a day.
> 
> This refreshes strings across the education screen, quick convert
header, asset overview CTA, claimable bonus tooltip, and conversion
success toast (now includes a secondary description line), and adjusts
the confirmation `PercentageRow` tooltip to include a tappable “Terms
apply” link to the bonus terms URL. Tests are updated to match the new
copy and label formatting.
