/* ══ ATMOSPHERIC SCRIM ════════════════════════════════════════
   Above 1,400 m the type inverts to snow-white while the render behind it is
   still a lit cloud sea and a white ridge. This is the air doing what the whole
   page is about: a soft directional deepening of the sky behind the column.
   No edge, no card. --scrim is driven from site.js by the SAME luminance that
   flips the type, so it can never appear while the type is still dark.
   The vertical fade is in px, not %, because these columns are ~2,500px tall
   and a percentage fade would leave the last screenful uncovered.            */
