/* ============================================================================
   THA — Talal El Hassan Architects
   Design system.

   Inter throughout; ink #181213, off-white #F7F7F2, light #EEECEC, gold #CC953D,
   grey #75716E, dark #3B3735. Square corners, no shadows, 12px wide-tracked
   small caps for navigation and labels, and a lot of empty space.

   Two rules hold everywhere in this file:

   1. Nothing is hidden. There is no `opacity: 0` and no `visibility: hidden` on
      content, so a section with no records, or a script that never arrives,
      leaves a readable page rather than an empty one.
   2. Exactly one thing is ever blurred: a statement panel's text wrapper as that
      panel leaves (`.ok-panel__textwrap.fade-out`), and the slideshow's arrows
      and counter as that section leaves (`.ok-slides__foot.fade-out`). The
      panel, the film, the page and every hover state stay sharp.
