/* xcaicx.com — built in the same house style as kosa8.com and anz33.com.
 *
 * Light, editorial, quiet: white space, one cool accent, prose held to a
 * readable measure, and the only dark things on the page being terminal blocks
 * and the demo viewport. It reads like a datasheet rather than a brochure,
 * which is what an OEM engineering lead is actually looking for.
 *
 * The accent is cyan rather than kosa8's amber. Two products from the same
 * shop should look related, not identical, and cyan reads as optical/technical
 * next to the hi-vis oranges that show up inside the demo overlays.
 *
 * No @font-face and no external requests. The CSP is
 * `default-src 'none'; style-src 'self'; script-src 'self'` and a page whose
 * pitch is "the inference never leaves the camera" has no business pulling
 * fonts off someone else's CDN.
