/* site/look-library.css — the "Reading room" look on the LIST views (the library and its search results, poets A-Z,
 * a poet's page, the library home). Companion to look.css (tokens) and look-reader.css (the reader's chrome and
 * type). Every rule is under html[data-look="reading-room"]; remove the attribute and the list views are exactly
 * styles.css again: app.js's wrappers (.lib-shell > .lib-top, .lib-rail, .lib-main, .lib-aside) are plain divs in
 * today's order, and body.rr-list (set by app.js's router on every non-poem, non-account route) is read only here.
 *
 * Why (Dom, 24 Oct, a 2000 px Safari window): the library was a 510 px column in a dark field, "such a waste of
 * space". From 1200 px the list views take the width the way the account page does: rail | centre | aside,
 * 1fr | 2fr | 1fr, 48 px gutters, 1760 px max (2100 px and 64 px from 1800). Below 1200 the wrappers dissolve
 * (display: contents) and the pieces flow as they always did; phones are untouched.
 *
 * Stage leftovers: the poem view's spotlight face is a position: fixed <video> at the right edge of the screen; the
 * router's body.rr-list hides any .vslot / stage dock still in the document on a list view and lays an opaque,
 * composited back-plate (body::after) behind the page so a frame WebKit kept after the element left cannot show
 * through the empty margins. The poem view (no rr-list) is untouched.
