🪅 Piñata Implementation

Issue: #306 feat: Add KE and MU locales to Express surface
Spec: 📦 View implementation spec

Summary
Kenya (KE) and Mauritius (MU) are already wired into the Express surface in io/www/src/fragment/locales.js (merged in PR adobecom#766, commit 78fbf5f, on the same Jira ticket MWPW-191681). No source change is required. To close out the issue cleanly, add a small regression test that asserts both regions remain part of the Express en_US family so a future cleanup cannot silently drop them.

Severity	Count	Files
🔴 Critical	0	—
🟠 Major	0	—
🔵 Nit	1	io/www/test/fragment/locales.test.js

Key Findings

• Asymmetric test coverage: tests 3 and 4 guard KE exclusion from non-Express surfaces but omit the equivalent check for MU — non-blocking, but worth fixing for symmetry.

Notes

This PR adds pure regression tests for existing functionality (KE and MU already wired into Express in PR adobecom#766). No production code changed. The core coverage — both locales present on Express, resolving to en_US, correct country names and flags — is correct and well-structured.

The file path (io/www/test/fragment/locales.test.js) falls outside the nala/ test tree; Nala E2E expertise does not directly apply, but the test quality principles (symmetric coverage, clear intent per test case) are universal.

Key Findings

• Missing .page.js in the new express/locales/ directory — the repeated page.evaluate(import(...)) calls could be extracted into a page-helper class to align with the three-file pattern (non-blocking).
