/**
 * Iris — a white-label skin. The client's identity on SazAI's elements. (data-skin="iris")
 *
 * THE NAME. An iris grows from a rhizome: a stem that runs sideways underground and sends a
 * flower up wherever it reaches. The network is buried and only the delivery points are
 * visible, which is what a distribution utility is.
 *
 * 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. This file re-lays the
 * page: the rail becomes a white bar under a two-colour rule, the hero becomes a full-bleed
 * band, cards and panels take the client's own graduated radius scale, and the footer becomes a
 * structural blue plane. Nothing is removed.
 *
 * WHERE THE VALUES COME FROM. No public brand book: a manual exists, an agency names it in a
 * portfolio, and nothing from it is published. No client page states any rule on third-party
 * use of the mark. Absence recorded, not filled. Every value here is a computed style measured
 * on the home and one institutional page (2026-09-11).
 *
 * THE SIGNATURE, AND IT IS ONE OBJECT REPEATED. A left-to-right gradient from the action colour
 * to the structural colour, used as a rule, as an underline and as a full-bleed band. It
 * appears eight times on the home and twenty-four on the institutional page. It is the only
 * gradient in the system and it does all the joining, so it is reproduced literally.
 *
 * THE GEOMETRY IS GRADUATED, NOT UNIFORM. 82.8% of elements are square, and the exceptions are
 * a deliberate scale: buttons 4px, cards 16px, statistic panels 32px, and true circles for photo
 * masks and segment chips. Flattening that to one radius would be a different brand, so the
 * scale is kept.
 *
 * TYPE. One freely licensed face carries display and body alike, separated only by weight, with
 * a single global negative tracking applied to everything. The stack names it honestly and
 * downloads nothing, and continues into Arabic, Hebrew and CJK for the five locales a
 * Latin-only stack would leave as tofu.
 *
 * CONTRAST. The action colour measures 2.2:1 on white and is therefore a fill that carries dark
 * ink, never body text and never a light-on-colour label at body size. The structural colour
 * clears AA on white and does carry text.
 *
 * NO MARKS. No logo, no wordmark, no company name anywhere, comments included.
 * 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. */

  /* ============ THE SIDE MENU LIES DOWN, AND THIS IS THE OTHER HALF OF THE BAR ============
     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. */
