/* ==========================================================================
   Snare — Feature index (sticky left nav + naturally-scrolling screenshots)
   A light section inside the dark-green site. The left pane is a sticky list
   of the six feature headings (with icons); the active one expands + highlights
   as you scroll. The right pane is the six screenshots, each with its longer
   description below, scrolling at native pace — no pin, no timer, no scroll-jack.
   feature-scroll.js only tracks which panel is centred to drive the highlight.
