/*
  DIRECTION CONTRACT — impeccable:direction-seed OCON-2026-01
  THESIS: The portfolio is the pitch — real aerial and ground coverage of
    real properties, shown at cinematic scale, so an agent decides to book
    before reading a word of copy.
  OWN-WORLD: Near-black charcoal ground throughout; warm brass/gold as the
    single accent (CTAs, active filter, italic display flourishes); Fraunces
    serif display (italic for accents) paired with Instrument Sans for
    UI/body; thin gold hairlines; full-bleed photography, no card chrome.
  STORY: Full-bleed aerial hero -> filter into real work -> stopped by one
    property shown from every angle -> same work reframed for social ->
    closed by a dark cinematic CTA into Book a Shoot.
  FIRST VIEWPORT: full-bleed looping aerial video, 70-80vh, dark gradient
    overlay bottom third, gold eyebrow, large italic Fraunces H1, one-line
    subhead, gold-outlined pill CTA bottom-left.
  FORM: editorial real-estate-photography portfolio (asymmetric masonry,
    lightbox, cinematic video viewer) — direction taken directly from the
    user's own pinned references (Urbanova, Luxury Image Estate Photography)
    and a fully detailed wireframe brief. No concept-seed roll: brief-pinned,
    precisely specified request.
  FINISH: unreviewed and undocumented is unfinished; this build ends with
    the finish review, the verdict, DESIGN.md, and every shipping raster
    carrying its provenance.
