   hub.css — section indexes, report meta bar, breadcrumbs, reading progress

   Everything here is emitted as raw HTML by scripts/build_docs.py or by
   overrides/main.html, with every figure already formatted in Python:

     .hub-stats / .hub-stat    headline counts on a section index
     .hub-notice               the disclaimer as one quiet line
     .hub-toolbar / .hub-filter the filter box above a card grid (hub.js)
     .hub-grid / .hub-card     one card per ticker
     .rmeta                    the chip bar + older/newer stepper on a report
     .crumbs                   the linked breadcrumb trail (main.html)
     .rp-progress              the reading-progress bar (hub.js)

   Uses the --fp-* tokens from extra.css so light and dark track together and
   keeps the card grammar kline.css / prices.css / ticker.css established:
   1px --fp-border, --fp-bg-card, a large radius.
