   I. Ada Crapper — Shared Immersive Framework
   File: css/immersive-framework.css
   ========================================================= */

/*
 * PURPOSE
 *
 * This file controls the shared architecture for every completed
 * immersive room on iadacrapper.com.
 *
 * It provides:
 *
 * - removal of the conventional visible header and footer,
 * - full available viewport coverage,
 * - automatic WordPress administration-bar allowance,
 * - one shared full-screen room canvas,
 * - consistent image scaling,
 * - hotspot positioning,
 * - overflow control,
 * - keyboard accessibility.
 *
 * Room-specific stylesheets should contain only:
 *
 * - hotspot positions,
 * - hotspot shapes,
 * - room-specific interaction effects.
