/* Shortsmith.
 *
 * One stylesheet, no framework. The whole interface is a left rail and a work
 * area, and the work area is one of four views - that is not enough structure
 * to earn a build step, and a build step is a thing that breaks between the
 * repository and the container.
 *
 * Layout is grid at the top level and flex inside it. Colours are all tokens,
 * because the caption preview has to tint itself from user-chosen values at
 * runtime and mixing hardcoded colours with those produces a panel that is
 * half themed.
