/* The Ledger — Sealed Annex hero (Casual layer).
 *
 * The lone trace of the Immersive layer in the Casual terminal: a sealed
 * world file that reads like a classified document in an exchange archive.
 * Resting state is desaturated — muted copy on --panel-2 behind a faint
 * diagonal SEALED stamp. Hover lifts the top-right corner (pure-CSS fold,
 * no blur / no JS animation libs) to reveal a live excerpt of the world
 * feed. Clicking walks into the Immersive layer.
 *
 * Scope: everything lives under #panel-annex. Layout placement (the casual
 * grid cell "immersive") and the Immersive-mode kill switch live in
 * styles.css; all visual styling lives here. */
