/*
Theme Name: Serac
Description: High-altitude mountaineering expedition company.
Version: 1.0
*/

/* ============================================================
   Serac's structural principle: after several themes compressed
   everything into one dense above-the-fold composition, this one
   deliberately goes long — a real multi-scene descent through the
   mountain (terrain flythrough -> live conditions -> route archive
   -> range index -> elevation data -> ice/rock detail -> story ->
   logistics -> team -> press -> journal -> CTA), each scene using
   its own device. The two devices unique to this theme: the
   elevation-profile sparkline (a small drawn SVG line per route,
   not a numeral/timecode/folio/stage-track like prior themes) and
   the grade stamp ("AD+ - 6,190M - EST. 2019"). Palette: glacier-
   navy black + pale ice + a warm alpenglow accent — a hue pairing
   not used before in this project.
