Optimize Venus mobile-first for its own most-used viewport (data-driven)

Elazar fleet directive 2026-07-07 (via pm-mars): ACT on collected viewport data — query Venus appEvents viewport distribution, identify THIS app's actual most-used viewport(s), ensure mobile-first layout is optimized for those real dimensions (not a generic breakpoint assumption). Deliverable: viewport distribution summary + targeted layout adjustments. Pull the distribution BEFORE the viewport-logging-removal WI cuts the emit. Not a tonight build.
