/**
 * LOCKED HEADER. The EvidenceOne logo (`LOGO_SVG`) is rendered here via
 * innerHTML and verified at runtime in componentDidLoad. There is no
 * brand-altering @Prop, no <slot>, and no other surface that allows the partner
 * to substitute or recolor the mark — this is intentional and must not be
 * relaxed without brand approval. (Functional state flags like
 * `canStartNewSession` are fine — they touch behavior, not the brand.)
 *
 * Defenses against logo swap:
 *   1. L4b source-hash check: the LOGO_SVG constant is hashed at build
 *      time and re-checked at mount; bundle byte-patches are caught.
 *   2. MutationObserver on the rendered <span class="eo-logo">: any
 *      runtime DOM tampering (`el.shadowRoot.querySelector('.eo-logo').
 *      innerHTML = '...'`) triggers `markBrandBroken()`, which causes
 *      AuthService.register() to throw and the root component to render
 *      its integrity-error state.
