 *
 * BRAND-LIGHT ON PURPOSE. docs/ops/umbrella-site.md §8: this domain may later
 * host the safety-share viewer, and naming the consumer brands here would
 * permanently associate the apex with them — telling a future share recipient
 * which brand the sender uses. No brand name, palette or mark appears on this
 * site. The accent below is the company's own, not any product's.
