Description: A custom personal portfolio theme for cinematographer Roan Buma — built around a single principle: the work should speak for itself. Homepage is a single reel. Everything else — grid, credits, stills, contact — recedes so the images and footage carry the page. Designed against Dieter Rams' ten principles of good design: useful, honest, unobtrusive, thorough, and as little design as possible.

   WordPress prints on the <img> tag (its intrinsic pixel size) as the
   effective CSS height once max-width shrinks the box — stretching
   anything that isn't already cropped to its display box (e.g. the
   `roan-wide` size, which is never hard-cropped) noticeably out of
   shape. video/iframe keep their own explicit sizing where it's set
   (e.g. .project-single__video iframe, .stills__stage img already
