/* iOS PWA standalone-mode safety net.
 *
 * The iOS env(safe-area-inset-top) value is unreliable in portrait mode
 * for installed PWAs — multiple iOS versions return 0 even when the page
 * extends past the safe area. Rather than fight that quirk, we
 * additionally apply a hardcoded top offset whenever we detect standalone
 * mode (no Safari chrome). The value is calibrated for the Dynamic Island
 * height plus breathing room; on older iPhones (notched or not) the extra
 * space is harmless.
 *
 * Combined with env() above, the top offset is roughly:
 *   • Regular Safari (display-mode: browser): 18px (env evaluates to 0,
 *     browser chrome handles status bar)
 *   • iOS PWA (display-mode: standalone): 18px + 60px = 78px hardcoded
 *     fallback IF env() is broken; or 18px + actual env if env works
