/* ==========================================================================
   The Roaring Lion -- 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 LIFT RIM, AND IT IS NOT DECORATION.

       Red earth. The lines are warm, so the lift rim is COOL -- the
       opposite trade from the boards drawn on a cold ground, and made
       for the same reason.

       AND IT IS WARM ON EVERY BOARD ON THIS SITE, which is the second half
       of the rule and was found in a picture on 2026-09-06. A COOL rim round a
       gold piece reads as a BLUE piece with a gold middle -- the enemy is a
       blue ring, and the two are one glance apart. The rim has to differ from
       the cell outline and from both players at once, and warm-and-bright is
       the only colour that is neither.

       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
 * eight 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.
