v2.3.0 Friendly, localized error handling; mobile and deploy improvements. - In-app error toasts now show calm, human, localized messages instead of raw chain assertions, mapping the common Blurt transaction errors (with a generic fallback) across all nine locales. - Fix long error messages overflowing the viewport on mobile. - Remove the obsolete out-of-bandwidth / Resource Credits modal, which does not apply to Blurt (transactions are gated by fees, not a resource-credit allowance). - Version the per-environment deploy config in the repo so the deploy jobs ship it. Classification: MINOR — user-facing features and fixes, no breaking changes.
