/**
 * Mangrove — a white-label skin. The client's identity on SazAI's elements. (data-skin="mangrove")
 *
 * THE NAME. A mangrove grows in salt water where nothing else will, and the land other species
 * later live on is land it built. An infrastructure business, named for the plant that is
 * infrastructure.
 *
 * 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, the hero ends in the client's single curved edge, the
 * emphasis inside a headline changes colour rather than weight, and the footer becomes a deep
 * slate plane over a dark red strip. Nothing is removed.
 *
 * WHERE THE VALUES COME FROM. No public brand book exists anywhere: eight guessed paths return
 * 404, a twenty-file sitemap index carries no brand or press URL, the privacy policy mentions
 * neither mark nor intellectual property, and there is no terms page. The only proprietary
 * assertion published is a registered-trademark glyph in the footer. Absence recorded, not
 * filled. Every value here is a computed style measured on the home and one interior page
 * (2026-09-11).
 *
 * THE SIGNATURE, AND IT IS ONE GESTURE. A headline is grey except for the phrase that carries
 * its meaning, and that phrase is red. Not bolder, not larger: a different colour inside the
 * same sentence. Everything else on the page is restraint, so that one move does all the work.
 *
 * THE CURVE. 87 to 91% of elements compute zero radius, and the exception is not a card corner:
 * it is the hero's own elliptical bottom edge, one wide shallow curve across the full width.
 * That curve is reproduced and nothing else is rounded.
 *
 * TYPE. Two openly licensed faces, so the stack can name them honestly. A semibold in capitals
 * carries the navigation, and a thin weight at large sizes carries the headings and every
 * numeral, which is what gives the pages their wide, quiet voice. Nothing is downloaded, and the
 * chain continues into Arabic, Hebrew and CJK for the five locales a Latin-only stack would
 * leave as tofu.
 *
 * 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. */
