/**
 * print.css — the one sheet the customer actually prints.
 *
 * Plan §3 (this file: "Small: hide chrome, expand `<details>`, show hrefs,
 * print the order summary legibly"), §5.13a ("`print.css` makes this screen
 * print legibly — it is the screen customers actually print"),
 * THEME-RULES.md §6.3, §11 item 37.
 *
 * ---------------------------------------------------------------------------
 * HAND-WRITTEN, NOT BUILT, AND OUTSIDE THE BYTE BUDGET
 * ---------------------------------------------------------------------------
 * `bin/build-css.mjs` does not touch this file and `bin/check-budgets.sh` does
 * not measure it. THEME-RULES.md §6.3 gives the reason and draws the line
 * carefully: `print.css` stays exempt "because it is genuinely small, genuinely
 * non-blocking, and printed at most once per visitor", and — the half that
 * matters — "neither exemption is a loophole: nothing that belongs in
 * `theme.css` may be parked anywhere to make a number fit." Nothing screen-
 * facing goes in here.
 *
 * It is enqueued with `media="print"`, so it is fetched at low priority and
 * never blocks a render.
 *
 * ---------------------------------------------------------------------------
 * WHAT A PRINTED PAGE IS FOR
 * ---------------------------------------------------------------------------
 * One reader, on paper, with no hover, no scroll, no JavaScript and no way to
 * open anything. So:
 *
 *   · CHROME GOES. A navigation bar on paper is a list of places the reader
 *     cannot go. The header, the footer, the filter bar, the CTA bands, the
 *     enquiry surface, the pagination and the total bar are all removed.
 *   · `<details>` OPENS. A collapsed disclosure prints as its summary alone,
 *     which on an order summary means the line items are simply missing.
 *     `[open]` is forced on every one.
 *   · LINK TARGETS APPEAR. A blue word is not a URL on paper. Every anchor in
 *     prose prints its href after it — with three deliberate exceptions below.
 *   · INK IS EXPENSIVE. Dark bands print as paper with ink text rather than as
 *     a solid black rectangle, and no image on the transaction screens prints
 *     at all.
 *
 * ---------------------------------------------------------------------------
 * THE ONE RULE THAT IS A SECURITY DECISION RATHER THAN A TYPOGRAPHIC ONE
 * ---------------------------------------------------------------------------
 * **`template-order.php` prints NO href, anywhere.** §5.13a: that URL carries
 * `?o={uuid}&t={token}`, the plugin sends `Referrer-Policy: no-referrer`, and
 * the template renders zero outbound links precisely so nothing can leak the
 * token. A print stylesheet that helpfully appended every `href` to its link
 * text would print the order token onto a sheet of paper — which is a leak the
 * headers cannot do anything about. So the href-expansion rule is scoped to
 * `.gwb-prose` and is switched off entirely on `.gwb-transaction`.
 *
 * The other two exceptions are ordinary: an anchor whose text already IS its
 * href (the telephone number) would print it twice, and a fragment link points
 * at somewhere on the same sheet.
