/*
 * EZPZ Texting — shared mobile UI enhancements.
 *
 * Goals (per PRD "Enhance mobile UI for better consistency across pages"):
 *  1. Visual consistency across pages (nav, buttons, cards, inputs, safe-area).
 *  2. Interactive elements meet 44px touch-target guidance on small screens.
 *  3. Lightweight perf hints: font smoothing, text-size-adjust lock, image defaults.
 *
 * Intentionally additive: this stylesheet is loaded AFTER each page's inline
 * <style>, so `:root` variable fallbacks and narrow media queries tighten
 * the existing look rather than rewriting it. Desktop is untouched.
