BankDeviceTrustBanner class

A contextual security banner driven by an externally-supplied state flag.

• BankDeviceTrustState.newDevice: amber left-border banner with an info icon, using BankTokens.warning (#FF9500) as the accent colour.
• BankDeviceTrustState.compromised: red left-border banner with a shield icon, using BankTokens.danger as the accent colour.

The banner reads its localised strings from strings when provided, or falls back to the ambient BankUiScope strings. The whole widget is annotated as a liveRegion so assistive technology announces the message when it appears.

BankDeviceTrustBanner(
  state: BankDeviceTrustState.newDevice,
  onDismiss: () => setState(() => _showBanner = false),
  onLearnMore: () => launchUrl(securityHelpUri),
)
