From c2289ce345a55024a1a6abfef800adc4406cbabd Mon Sep 17 00:00:00 2001 From: Khalid Al-Mutawa Date: Fri, 22 May 2026 04:31:33 +0700 Subject: [PATCH] feat: add responsive layout smoke tests for mobile and tablet viewports [STU-175] 20 tests covering 3 pages (landing, login, candidate portal) across mobile (390x844) and tablet (768x1024) viewports with assertions for horizontal overflow, readable text, tap target sizing, and navigation adaptation (mobile tab bar vs sidebar). Also adds a tablet project (768x1024, 2x scale) to Playwright config.
