/* ===========================================================================
   GL·9 Strata — Selected Works, embedded in the portfolio (section 05).
   A scroll-scrubbed WebGL journey: eleven works walk the stage in depth,
   each with its own choreography, then settle into a quiet background shelf.
   Driven by the tall #work section's own scroll progress (sticky viewport).
   All layers are absolute WITHIN .st-stage so nothing leaks into the page.
