/* ============================================================
   Sillage's structural principle: the page itself is shaped like
   a fragrance pyramid. Top-note sections run full-width and fast;
   heart-note sections settle to a standard measure; base-note
   sections narrow to a slow, single reading column. Section width
   and rhythm actually change as you scroll — no prior theme in
   this project has varied its own measure like this.
   Palette is aubergine-wine black + warm gold + a blush accent
   used only for glow moments — a hue family not used before.
