/* ============================================================
     SERVICES SECTION — design tokens
     Palette is built for a dark, technical AI/automation identity:
     - bg: near-black, blue-tinted (not pure #000 → feels engineered, not flat)
     - accent: "signal blue" — reads as data / pipeline / signal
     - accent-2: warm amber — the "output" / result color, used sparingly
     Typography: Space Grotesk (display, geometric/technical) +
     Inter (body) + JetBrains Mono (labels — echoes the tech-pill tags
     already used on the Skills section of the live site).
