/* index2.css — VectorOS landing «Командный пункт» (/index-2 redesign)
   =====================================================================
   Self-contained page stylesheet: this page loads ONLY colors_and_type.css
   + this file. Chrome blocks (topbar, footer) are ported verbatim from
   landing.css / landing-v2.css so the page stays visually identical to
   sibling pages; section styling is new.

   Art direction: the page is one continuous instrument. A fixed telemetry
   rail tracks the frames (sections); every frame opens with a mono folio
   row; orange #FF4F00 appears only as signal (ticks, anomaly marks, the
   one underlined phrase, the LIVE dot). Motion is linear and plays
   once per entry; the only loops are the LIVE dot pulse and the neutral
   pull-quote sweep. Phone-interior motion mimics Telegram (exempt, like
   the radius exemption).

   JS contracts kept intact (do not rename these classes):
     .pain-grid / .src-grid          → mobile-v2.js (m-rot scroll rows)
     #how .tg-grid .tg-card .tg-msg  → tg-animator.js
     #refs-grid .ref-cell            → refs-animator.js
     .pos-chart .pc-node--us         → inline position script
     #vphone .tgx__* .phone          → phone-demo.js
     .topbar--reveal / --on-light    → inline topbar scripts
