/**
 * Qing Blog Head widget styles.
 *
 * The journal banner: a full-bleed photograph, a wash over it, and the
 * eyebrow / serif headline / lede stack on top. Ported from the static
 * journal page (.blogHead / .blogHead__media / .blogHead__lede) with the
 * classes namespaced to .qing-blogHead.
 *
 * Every control writes a CSS custom property on the wrapper, and this file
 * declares the same properties as its own defaults, so an untouched control
 * falls back to the static page value rather than to nothing.
 *
 * Two things the static page got wrong are fixed here rather than ported:
 *
 *  - <figure> keeps the browser default margin (1em 40px). On the absolutely
 *    positioned media box that margin pulled all four edges inward and the
 *    section background showed through as a dark frame. The reset below
 *    zeroes it.
 *  - The wash was the same weight top and bottom, so the type sat on whatever
 *    the photograph happened to be doing behind it. It is weighted to the
 *    centre instead: darkest where the words are, lighter at the edges.
