/* tokens.css -- the skin tokens, each with its default.
 *
 * This file is the whole list: what a skin may redefine is what is
 * declared here, and SKIN-API.md (apps/sluice/) says what each one
 * promises.  A skinned sluice loads it first, then skinned.css, which
 * says what each part of the sluice is in these tokens, then the skin.
 * A page that holds a sluice in a frame and wants to look of a piece
 * with it loads this file and the same skin, and lays itself out in
 * the same tokens.
 *
 * The defaults ARE the house look, "workstation": a 1980s Lisp
 * workstation's screen.  Black ink on a near-white ground; panes tiled
 * edge to edge and ruled off in single pixels; labels in reverse
 * video; what is under the pointer boxed rather than tinted; nothing
 * rounded, nothing shaded, and no colour but for what has gone wrong.
 *
 * A skin is a file beside this one, skin-<name>.css, holding a :root
 * block like the one below with the tokens it changes.
 *
 * The tokens are named --pl- after the page they were first drawn
 * for, the prompt lab.
