/* ==========================================================================
   tak.zyntelligent.com — TAK (Team Awareness Kit) intro site

   Design system generated with the ui-ux-pro-max skill
   (search.py "tactical military command control situational awareness"
    --design-system --variance 7 --motion 4 --density 6, then
    "military defense tactical dark terminal" --domain style)

     Pattern    Hero + Features + CTA (sticky hero CTA + bottom CTA)
     Style      Cyberpunk UI (matched entry: terminal/HUD aesthetic, angular
                shapes, monospace, scanline overlay) with its neon palette
                REJECTED — a defence-services company is not a game. The
                structural cues are kept: square corners, HUD corner brackets,
                a map graticule under everything, mono readouts.
     Colour     No military/tactical palette exists in the colour database
                (nearest matches were media apps), so the palette is an
                extension of the previous one: near-black graphite surfaces,
                brand gold kept as the action colour, and the MIL-STD-2525
                affiliation hues (green own / blue route / red threat) kept
                for status rather than decoration.
     Type       Chakra Petch (display — the only candidate carrying both a
                Thai and a Latin subset, squarish and technical) / Inter +
                Noto Sans Thai (body) / JetBrains Mono (labels and readouts).
                Mono stacks list Noto Sans Thai after JetBrains Mono so Latin
                renders monospaced while Thai glyphs fall back correctly.
     Motion     Standard tier: stagger reveal 300-450ms, back.out(1.4)
     Density    Standard: 16-64px spacing scale

   Every text/background pair below was measured; all body pairs are >= 4.5:1
   and white-on-accent is 4.9:1. Gold #A16207 is a FILL ONLY (3.4:1 as text) —
   use --accent-text for gold text on dark.
