The narrow-screen rules now pin the glow to its panel box; the stacks still scroll for genuinely tall content such as an expanded DISPLAY panel, and the Context radio popover is not clipped. `src/ui/panelRails.test.mjs` pins the rule against every 720px media block. - Enable responsive trackpad pinch zoom on the globe. Browser pixel-mode `Ctrl+wheel` pinch gestures now reach Cesium with bounded amplification, while ordinary wheel, line-mode and touch-pinch inputs retain their existing behavior; the listener is removed with the application scene. - Report AIS speed and course that carry the standard "not available" code as unknown instead of 102.3 knots and 360 degrees.
