/* ═══════════════════════════════════════════════════════════════════════
   PIXELPRO PRODUCTIONS · DESIGN SYSTEM  (locked 2026-09-19)
   Single stylesheet. Formerly style.css + 3 review overlays; merged after
   the client locked v3.5. The pre-merge layers are kept in /.archive/ for
   provenance — do not load them.

   ── TYPOGRAPHY ────────────────────────────────────────────────────────
   Nav 16px / w600 / pure white.  Benchmarked against 9 competitor sites
   (measured with Playwright, 2026-09): AVI-SPL 15px, Jacobs 16, Ford AV 16,
   ROE Visual 16. Apple's 12px was the wrong reference for a Pro AV buyer
   in the 40-60 age band — do not shrink this back.
   Body 16px / 1.7.  H2 unified at 60px.  Hero 116px.
   Display face: Manrope 500.  Signature emphasis: Instrument Serif italic
   (CJK has no glyphs there — .zh .em falls back to the display face).

   ── CONTRAST POLARITY ─────────────────────────────────────────────────
   Dark hero + footer, LIGHT reading zones (.zone-light). Competitor body-
   area brightness measured at Turner 85%, ROE 79%, AVI-SPL 78%,
   Diversified 77%. An all-dark body (the original spec read ~5%) hurts
   sustained reading for the target age band; positive polarity is the
   researched default (NN/g; Piepenbrock 2013; Sethi 2023).

   ── RED DISCIPLINE (v3.5) ─────────────────────────────────────────────
   Red is a full brand colour on ACTION and SIGNATURE elements only, and
   is reverted on INFORMATION elements. Element count: v3 had 46, v3.5 has
   13 (-72%). Rationale: PixelPro red vs ROE Visual red measure ΔE 1.43
   (CIE76) — visually indistinguishable, so saturating the page invites a
   commercial collision with a brand we also sell alongside.
     --signal      #e30613  fills, borders, marks
     --signal-lift #f43b46  red TEXT on dark  (brand red is 3.99:1 = AA fail)
     --signal-deep #c2050e  hover on red fills (6.32:1)
   Every colour pair in this file was checked for WCAG 2.1 AA (4.5:1).
