/* =========================================================================
     OpenAdviser P3 — single-viewport stage
     - Body never scrolls. Sections transition in 3D in place.
     - Canvas heliograph field sits behind
       everything, fixed. Foreground document remains readable on fallback.

     WCAG / NN-Norman pass (v2):
     - Darkened --bg-primary to #0a0c10 — text-primary now ~16.4:1 (AAA),
       text-secondary ~12.0:1 (AAA), text-tertiary lifted to 0.78 alpha
       to clear 4.5:1 (AA) for the small mono labels.
     - Nav-dot hit targets enlarged to 36×36 (AAA touch).
     - aria-current="true" announced on the active section dot.
     - Slide order, counter and progress preserve system-status visibility.
