fix: resolve intermittent narrow rendering on Chrome iOS

Remove the zoom JS hack that triggered bad viewport relayout on
visibilitychange, replace vw units with % for stable sizing across
pinch-zoom and address bar changes, add dvh fallbacks for correct
iOS viewport height, set min-width floor, and constrain fixed
background elements to prevent phantom overflow.
