Subject: feat(client): redesign frontend with TailwindCSS v4
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace inline styles with TailwindCSS, implementing a cohesive Japanese-inspired
design system with custom colors (cream, teal primary), typography (Fraunces,
DM Sans), and animations. Update all pages and components with consistent styling,
improve accessibility by adding aria-hidden to decorative SVGs, and configure
Biome for Tailwind CSS syntax support.
