/* ==========================================================================
   Mountain Picker — the Profile Line (Geography)
   One of two pages on profile-line-engine.js (the other is river-picker, which
   uses the same engine with revealStyle 'source-to-sea'). The stage is a
   side-on cross-section drawn to TRUE relative scale: every peak's height in
   the scene IS its elevation, measured against a fixed metre axis. A climber
   walks the skyline left to right, decelerates and stops on one summit, where
   a flag plants and the altitude is measured off the axis.
   ⚠️ The climber's path is an OPEN line across a scattered field — not a
   pointer on a loop — which is what keeps this from being a wheel in disguise.
   Page chrome is theme-aware (var(--theme-*)); the rock, snow and sky stay
   fixed — they are a physical landscape, not themed surfaces.
   ⚖️ Original artwork only: plain stylised landform silhouettes. No photos.
