/* ============================================================
   Orion Tech Solutions — style.css
   Single theme: OTS Green page, white text, #FFA500 accent.
   Two block colors total: green (page) and cream.

   Accent inversion rule: #FFA500 passes on green surfaces
   (5.1:1 page, 6.6:1 deep, 3.9:1 raised — components only there)
   and FAILS on cream/white (1.5–2.0:1). Inside .block-cream the
   scoped tokens swap the accent role to OTS Green — orange never
   crosses into a light field as text, hairline, or ring.
