/* Pointglass — pointglasslidar.com
 * Version: 1.0
 *
 * Tokens come from brand/BRAND.md. Two rules hold the design together:
 *   1. Cyan is the ONLY accent. It marks the interactive and the measured.
 *   2. The elevation ramp colours DATA and nothing else — never chrome,
 *      never behind text.
 *
 * The page borrows the application's own furniture: a menu-bar-thin header, a
 * status bar pinned to the bottom, and section headers drawn like panel
 * headers. That is the design's one bold move; everything else stays quiet.
