/*
 * SAVRN progressive navigation identity — 2026-07-30
 *
 * Scope is intentionally narrow:
 *   - Home keeps the quiet white navigation rail.
 *   - Entering an operating workspace turns only the left rail SAVRN blue.
 *   - Page canvases, cards, headers, and local workspace palettes are untouched.
