/* =========================================================================
   CSA Hero Slider — Prentiss
   Geometry and control styling reproduce the Slide Anything / Owl "white"
   theme banner that is on pcepa.com today:
     · slide height = 35% of the slider width
     · banner drawn at 100% width from the top-left, no repeat
     · #eee frame with a 6px transparent inset
     · 30x40 arrows inset 10px, rgba(0,0,0,.3) -> .8 on hover
     · 10px dots, rgba(0,0,0,.2) -> .5 active, on a 22px strip below
   Everything else here is accessibility and theme-proofing.
