/* ============================================================================
 * DiaPredict - Liquid Glass v2 stylesheet
 *
 * Layout strategy
 * ----------------
 * - Section tokens (colors, blur, ambient blobs, risk semantic palette) live
 *   in :root with a dark-mode override at @media (prefers-color-scheme: dark).
 * - Glass surfaces use --glass + backdrop-filter: blur(var(--gblur)) saturate().
 *   Stronger surfaces use --glass-strong. Inner highlights use --ghi and
 *   inset shadows on the box-shadow shorthand.
 * - Spacing: a 4/8/12/16/24/32/48/64 scale. Sections get 40px or 90px vertical
 *   padding depending on whether a nav-fixed offset is needed.
 * - The page is a single-column flow; the only nested grid is the console
 *   (form 2fr + result 1fr, sticky) and the history (trend 1fr + timeline 2fr).
 *
 * Performance
 * -----------
 * - backdrop-filter is limited to: nav, cards, result panel, timeline cards.
 * - Heavy animation is opt-in via @media (prefers-reduced-motion: no-preference)
 *   so the reduced-motion branch is the default path.
 * ========================================================================= */
