/* open-dictate: website.
   The same skeleton as openaudiovisual.com (ink, bone, one signal color, Archivo + DM Mono,
   numbered sections under a five-line staff), with Dictate's own signal: the caret.
   Two colors encode meaning and appear only where they do:
     --sig   a text cursor, a glossary pair that fired, something that works today
     --flag  something left as heard, planned, or never allowed to leave the Mac
   Ornament = things the pipeline actually does: a caret, a waveform, the socket's JSON. */

   always: 64 KB, preloaded); otherwise the page keeps its fallback rather than reflowing under the reader. */
