- Cart quantity buttons: h-8→h-11 w-8→w-11 (44px touch target), rounded-xl, active:scale-95
- StorefrontFooter newsletter: responsive w-full sm:w-52 lg:w-64, aria-label, larger touch targets
- StorefrontHeader mobile nav: padding px-6→px-4 py-6→py-5
- AdminTable: overflow-x-auto + min-w-[600px] for horizontal scroll
- AdminOrdersPanel: same table overflow fix
- AdminLayout: mobile px-4 sm:px-6 py-6 sm:py-10
- AdminFilterTabs: responsive text/text sizes
- AdminSidebar hamburger: h-10→h-11 w-10→w-11 (44px touch target)
- DashboardClient: grid gap-3 sm:gap-4, responsive stat text
- OrderEditForm: grid-cols-1 sm:grid-cols-2 (was 2, breaks on mobile)
- BillingClient: min-h-[44px] on select/button
- ProductsClient: h-32 sm:h-40 responsive image height
- StopCard: line-clamp-2 instead of line-clamp-1 on location
- CommunicationsPage: tabs wrapped in overflow-x-auto
- Checkout page: grid breakpoint md not lg
- Tuxedo page: SectionHeader mobile-first, feature grid grid-cols-1 sm:2, label visible
- Tuxedo stats: text-3xl sm:text-4xl

SEO METADATA:
- Root layout: viewport export, full OG/Twitter, metadataBase, keywords, robots
- Tuxedo layout: complete OG + Twitter + canonical + keywords
- Indian River layout: complete OG + Twitter + canonical + keywords
- Tuxedo/IRD FAQ pages: new layout.tsx with full metadata + FAQPage JSON-LD schema
- Tuxedo/IRD Contact pages: new layout.tsx with full metadata
