/* ping.css — Carino Ping. Fleet design tokens: single gold accent on near
   black, IBM Plex Sans/Mono, Red Hat Display for the brand. Green reads "good
   line", red reads "loss" — the Data Viz convention, not decoration.

   Replaces the Tailwind play CDN the previous version loaded on every page
   view. That script compiles a stylesheet in the browser on every load, warns
   in the console that it is not for production, and put a Google Fonts @import
   in the page — three things the fleet conventions each rule out on their own.

   SHAPE: this is a fixed-viewport app, not a document. The page itself never
   scrolls — `body` is exactly the viewport tall with overflow hidden, the navbar
   takes its 60px, and `.app` takes the rest. Anything that can outgrow its box
   (the target cards, the sample log) scrolls inside its own pane, and the long
   prose lives in a dialog rather than below the fold. */
