/*
 * Homepage hero photos ([oak_hero_slides]).
 * - The frame's bottom-right corner sweeps round like the oak leaf in the logo,
 *   and a gold line follows that curve, drawing itself once as the page loads.
 * - Photos cross-fade with a slow settle. The progress line under the current
 *   place is a CSS animation; hero-slides.js shows the next photo when it ends,
 *   so hovering the photos holds them.
