/* v5000.85 — root sizing rework.
 *
 * Before: html and body had `height: 100%` and #app was a flex column.
 * Result: body was locked to exactly viewport-height, the page scroll
 * happened inside #app rather than on window, and `position: sticky`
 * had no viewport-sized scroll context to stick to.
 *
 * Now: html/body grow naturally with content; #app uses block layout
 * with a min-height so any landing-style empty state still fills the
 * screen. Sticky elements now have a real viewport scroll context.
