/* Latch — latch.aurionblack.com
   Hand-written, no framework, no build step, and NOTHING loaded from anywhere else.
   🔴 That last part is load-bearing, not taste: the app's whole pitch is that it makes
   zero outbound calls, and a landing page that pulls a webfont or an analytics beacon
   while saying so would be the first thing a sceptical reader checks and the first
   promise the project breaks. System font stack, inline SVG, self-hosted images only. */
