/* Hallmark · pre-emit critique: P3 H4 E4 S4 R5 V3 · weakest: V, retained the Cognito form geometry so the preview represents deployable branding. */
/* User-requested homepage chrome: shared stars, orbiting light and glass bar preserve the existing SiSite design. These enhancements are preview-only, beyond Cognito managed-login branding. */
/* Hallmark · waive 7b · surface: absolute, readable light form and nav text · the user explicitly requested the same black canvas as the SiSite homepage atmosphere. */
/* Hallmark · answered F24 · the glass bar keeps the homepage's thin rim and shallow shadow so its navigation remains visually identical. */
