/* Ada — marketing site.
   Design: the product's claim is measurable, so the page is built like an instrument
   readout rather than a landing page — hairline rules, mono labels, tabular figures.
   Colour is functional: green is Ada's data, amber is the comparison arm. Fonts are
   served from this repo (Ada ships offline-safe pages; its own site shouldn't beg a CDN). */
