/* strip v2 2026-09-14
   Silvatech Lab register. Load AFTER Bootstrap with one link:
   <link rel="stylesheet" href="https://silvatech.bz/brand/silvatech-ui.css">
   Existing .btn, .btn-primary, .btn-secondary and .card markup is supported.
   Use .svt-whatsapp on a wa.me anchor; .svt-footer and .svt-legal for the footer.
   Self-contained: no companion stylesheet, font provider or runtime is required.
   Edit Lab rules here; the shared strip block at the end is generated from ecosystem-strip.css.
   Font stacks degrade locally; this file does not contact a font provider.
   Canonical contract: SILVATECH-ECOSYSTEM.md sections 2-4. No runtime required. */
