stage.css

/* The stage: the figure, the card and the expand dialog, shared by every page that draws a
   data block (spec §4). Loaded relatively — `<link rel="stylesheet" href="../stage.css">` —
   after the page's own inline <style>, so the page's tokens are defined before these rules
   use them and a page rule and a stage rule of equal weight still resolve the way they did
   when both lived in the one block. The page keeps `.figure-section`, `.figcap` and its
   prose; everything below belongs to the stage and is edited in this one place.

   The design tokens (--ground, --raise, --rule, --ink, --dim, --c-*) and the `.mono` face
   come from the page: this file names them, it does not define them. */
  /* The path line and Expand share a row: the control belongs beside the thing it acts on,
     not tucked in the card's footer — Expand opens the whole stage, not just the card. */
  /* Three columns: the path, the history, Expand. The middle one is the transport the
     script builds, and it sits over the seam between canvas and card; in the dialog Expand
     is turned into nothing and the right column stays, so the control does not move.
     Each names its own column rather than trusting the order it was written in. Auto
     placement fills the tracks from the items present, so the moment one of the three is
     not there — the path is not, below 860px — the other two slide left and the transport
     stops sitting over the seam. A column named is a column kept. */
  /* The row is as tall as the history's slab from the first paint — its 28px buttons, .25rem of
     padding above and below and a 1px border each side — because stage.js builds the history
     after the page has painted, and a row that grew then pushed the whole stage down by the
     difference. */

       on both, which is what makes the shares equal rather than proportional to what is

       argument that a percentage split shrank the dialog's canvas below its on-page size.

       already the smaller of the two, and a stage that changes its proportions when it is
       expanded is a second layout to learn. What Expand gains on a phone is the whole

       and a card floating a few pixels in reads as neither one nor the other. So the border,
       the radius and the margin go, the backdrop stops showing at all, and the sheet is the

       was both shorter and narrower than the page's own, so the control gave back less
       than it took. At the full screen the height is the page's — 285 against 288 on an
       iPhone 13, the head row and the gutter accounting for the three — and the width is
       374 against 335. Wider, not taller, is what a phone has to give.
       dvh and not svh: the page behind a modal cannot scroll, so the browser's own bar is
       frozen wherever it stood when the sheet opened, and the dynamic unit is simply the
       screen as it is at that moment. A gutter stays — the path line, the transport and the
