/* ==========================================================================
   OFFICE LOCATION CARDS
   Layered over the base card in main.css (section 15). Every hover from
   there is kept -- the city photo fading in and settling, the lift, the
   green border, the text easing right -- and refined: the photo now sits
   behind a veil so the address stays readable over it.

   Added: a gradient border that turns on hover, a pointer-following glow
   and tilt (js/office-locations.js sets --mx/--my/--rx/--ry), an outlined
   country code, a phone icon and a filled map button.

   Selectors lead with .locations-grid so they outrank main.css, and the
   copies of it merged into the service-page bundles, without !important.
