/* Lepo — lepohealth.app
 * One shared visual system, no build step and no external requests.
 *
 * The palette is the H1 app icon, "Evening to Aurora" (tools/AppIcon/lepo-icon-h1.svg):
 * a kaamos sky, the Lepo line running amber → rose → violet → aurora teal, and a cream
 * point for today. The palette and its rules are in docs/DESIGN_SYSTEM.md § Brand Identity;
 * change it there first, then in the icon and here, so the three read as one brand.
 * Everything is styled from this file because the CSP in _headers allows
 * style-src 'self' only: no <style> blocks, no style="" attributes.
