   The Whole Armour -- this board's own look  (styles.css)
   ==========================================================================
   Shared chrome comes from theme.css, shell.css and board/board.css. This file
   holds ONLY what is particular to this board -- 01-Architecture.md §9: Go
   stones and Mancala seeds are not the same object, so a board's own colours
   and piece artwork are never shared.

   Every colour and measurement is a token in the block below, so changing the
   look is one place rather than a hunt.

   THE PAGE MUST NEVER SCROLL, and nothing may ever scroll sideways. .stage is
   the only element allowed to grow or shrink. The max-height: 299px exception
   in Standards.md §5 applies unchanged.
   ========================================================================== */

/*
   EVERY LINE BELOW IS A TOKEN, AND THAT IS THE WHOLE CUSTOMISATION SURFACE.

   board.css already wires these to the real class hooks -- `.board__piece` gets
   `.is-side-0`, `.is-side-1` and so on from sprites.js, and an alternating cell
   gets `.is-alt`. A game that writes its own `.board__piece--0` rule instead is
   writing a selector that matches nothing: the page renders, the pieces are the
   shared gold and blue, and no tool anywhere reports a thing. That was the
   first version of this scaffold, and it is why the token list is the only
   thing here.

       The two players' colours. NOT their shapes: those come from sprites.js
       and are the signal that survives a colour-blind eye, a photocopy and
       Windows High Contrast. Change a colour here and rename the side in
       rules.js to match, or the board will say "Gold to play" in blue.

       Each colour has an EDGE, and it is not decoration: a piece is drawn with
       `paint-order: stroke`, so the darker edge is what keeps a pale piece
       legible against a pale square.

/*
 * THE BOARD'S SIZE IS NOT THIS FILE'S BUSINESS, AND THAT IS DELIBERATE.
 *
 * board.css already gives .board__frame `flex: 1 1 auto; min-height: 0` and the
 * SVG carries `preserveAspectRatio="xMidYMid meet"`, so the browser fits the
 * board into whatever space the column leaves -- at every viewport, for all
 * seven topologies, with no media query and no JavaScript.
 *
 * A per-game override here fights that. The first version of this scaffold
 * capped the frame at `calc(100vh - 16rem)`, which on a 360px-tall phone in
 * landscape is 104px: the board shrank into the top-left corner with two-thirds
 * of the screen empty. NOTHING FAILED. There was no overflow, no scrolling and
 * no console error -- every automated check passed and the game was unplayable.
 * Only the screenshot showed it (2026-09-03).
 *
 * If a board genuinely needs a different shape, change its viewBox in the
 * TOPOLOGY, which is the one place that knows the geometry.
 */

/*
 * Nothing else belongs here yet, and that is the point: board.css draws the
 * surface, the cells, the pieces, the three markers and the panels from the
 * tokens above. Add a rule here only for something this board has that no
 * other board does.
 */

/*
 * THE ARMOUR'S NUMBER, DRAWN ON THE SOLDIER.
 *
 * Oware's finding, inherited: `board.css` draws ink as `--text-dim`, which is
 * right for a track square's number printed in a corner and wrong on top of a
 * gold tile. This game's ink is the child's own soldiers' strength -- the one
 * thing the child needs to read at a glance -- so it is read against the two
 * piece colours rather than against the board:
 *   #1b1108 on --piece-0 #ffd45c   13.1:1
 *   #1b1108 on --piece-1 #7fc8ff   10.3:1
 * (the blue only ever carries ink once a soldier has been revealed.)

/*
 * A revealed Snare is drawn as a mine and the Banner as a flag, both from
 * sprites.js. The mine's own fill would make its glyph unreadable, so the two
 * immobile kinds carry NO ink -- see glyphAt() in Scripts.js, which draws
 * `!` and `B` only on the child's own veiled tiles.
