# DS-010 — Reusable WALKA trust strip

Status: COMPLETED
Issue: #109
PR: #115
Parent UI Task Master: #85
Implementation branch: `agent/ds-010-trust-strip`

## Delivered

- Added `WalkaTrustStrip` under `mobile/lib/design_system/components/cards/`.
- Centralizes navy premium surface, shared WALKA radius, spacing and default white/gold content themes.
- Accepts arbitrary child benefit widgets so the design system does not embed product claims.
- Adapts from one compact column to two standard columns and up to four wide columns using bounded-width layout rules.
- Focused widget tests cover surface tokens, child preservation, responsive wrapping, semantics and inherited text/icon themes.

## Guardrails

- No trust/benefit claims are hard-coded in the component.
- No feature-page integration.
- No Product Master, backend, Amazon boundary or protected `Images/` changes.
