/**
 * Jacarandá — a white-label skin. The client's identity on SazAI's elements. (data-skin="jacaranda")
 *
 * THE NAME. The jacarandá turns a whole avenue one colour for three weeks a year and is bare
 * the rest of it. That is this identity: a near-monochrome grid where a single saturated
 * gesture appears on the one thing you are meant to press, and nowhere else.
 *
 * THE RULE (Rames, 2026-09-11): elements and tokens.css are the guardrails; inside them the
 * skin may change whatever it wants, but it must keep every element. So this file re-lays the
 * page: the rail becomes a slim near-black chrome bar, the hero goes to a very large display
 * head on white, the panels become a hard grid of square cells, and the footer becomes a dark
 * plane. Nothing is removed.
 *
 * WHERE THE VALUES COME FROM. The client's public brand book, which is open and unusually
 * complete, cross-read against computed styles on their home and one interior page
 * (2026-09-11). 96.6% of home elements and 97.8% of interior elements compute border-radius 0,
 * so the square corner is structural, not stylistic. The accent rides on exactly one gesture,
 * a lime gradient on primary actions; a second green paints one fill on the entire page.
 * Where the book and the served page disagree the book wins: the book specifies the gradient
 * at 40 degrees, the site paints it at 90, and 40 is what ships here.
 *
 * TYPE. One face carries everything from body to a 120px display head, and the hierarchy comes
 * from scale and weight rather than from a second family. The book names three faces and all
 * three are freely licensed, so the stack can name the real one. Nothing is downloaded: it
 * renders where installed and falls back otherwise, and the chain continues into Arabic,
 * Hebrew and CJK, because this product serves eleven locales.
 *
 * CONTRAST. The lime gradient is an action surface, never a text ground: its lightest stop
 * against white measures under 1.5:1, so labels on it are always near-black. The accent is
 * never ink on white.
 *
 * NO MARKS. No logo, no wordmark, no company name anywhere, comments included: a skin sheet is
 * served verbatim, so a name in a comment is a name in the served bytes. The client's book is
 * explicit that their mark may be used only under an existing partnership, which is one more
 * reason the identity here is carried by shape, scale and colour alone.
 *
 * DIRECTION. Every inline offset is logical, so the skin flips with the document in ar and he.

  /* ===================== THE RAIL BECOMES A BAR, AND IT IS A GRID =====================
     Corrected 2026-09-11 after rendering the first skin on a served page and measuring it.
     My first version made the rail `display:flex` with a fixed `block-size`, and the children
     spilled down the page: `.flex-component` landed at y=354 and the nav mount at y=414 with
     the bar ending at y=84. The cause is one line of the HOST's own CSS: `.sazai-rail-chrome`
     computes `display: contents`, so it is not a box — its descendants are promoted into
     whatever formatting context the rail declares, they bring their own height, and 84px does
     not hold them. The reference skin solved this before me and I had read the file:
     a GRID with named areas, so the chrome gets a row of its OWN below the bar row, every
     child is placed explicitly, and the chrome is given a real `display` so it stops being
     `contents`. No fixed height on the rail: the rows size themselves. */

     Measured 2026-09-11: with the grid alone the bar rendered 842px tall. The chrome row got a
     row of its own, correctly, and then the side-menu component kept its own vertical layout
     inside it. A bar is not a bar until the component in it lies down. 48 of the reference
     skin's 139 rules are this conversion, and it is brand-independent: what follows is that
     structure, parameterised by this skin's own tokens. Every part below is one the component
     publishes; nothing reaches into its internals. */
