Introduce resolution-aware UI scaling to keep fonts, glyphs, and panel chrome readable and aligned above 1920×1080. Adds a new components/layout.js that sets --co-ui-scale (baseline 1920×1080) on load/resize and exposes CO_Layout.update; index.html now loads it and app.js triggers updates onBrowserShown and on window resize. styles.css converts many fixed px values to calc()/em driven by --co-ui-scale, removes the old pixel-floor media queries and clamp caps, and scales borders, spacing, and font sizes. controller-glyphs.js multiplies glyph dimensions by the UI scale so controller icons grow correctly. Changes address small/drifting server browser content on high-res and ultrawide displays.
