/* ==========================================================================
   Arcanaverse Personal Website — Design System / Layout (v4)
   Concept: Live Systems Interface × Editorial Dossier (sticky media)

   v4 keeps v3's facts, palette and restraint rules, but replaces the
   "everything is a flat, static document" reading with a small set of real
   states: the header tracks which section you're in (scrollspy), Career
   dims/lights the chapter nearest the viewport as you scroll, and Selected
   Work pins each project's media while its text scrolls past — all via
   native CSS (position: sticky, :has()) plus two small IntersectionObservers
   in main.js. Nothing here is decorative motion; every state change encodes
   "where you are."

   Rhythm this time comes from WIDTH and a single tonal shift, not from a
   repeated eyebrow-label + hairline template:
     Hero            — full canvas
     Current Focus   — narrow column, Build lead + System/Teach secondary row
     Career           — full canvas, vertical timeline
     Selected Work    — full canvas, one shade lighter (--surface) background
     Closing          — narrow column, About + Contact merged

   Still true, unconditionally: no gradients, glow, glassmorphism, heavy
   shadow, card grids, dashboards, stock imagery/illustration, logos,
   decorative pills, or scroll-triggered reveal animation. The one deliberate
   surface change (Selected Work) is a tone shift, not a dark plate.
