/*
 * Page-specific styles for the Product Template Expansion Detail page.
 * Sandbox-only reference at /product-template-expansion-detail
 * (and rendered for any /products/:product/expansions/:slug match).
 *
 * Port of the handoff's inline <style> block in
 * `Imaginando Product Template Expansion Detail.html`. `--pack-hue`
 * cascades from `<main>` through every selector below that uses
 * var(--pack-hue) — every pack shares the site's global --accent
 * (set once below, no per-pack value), so recolouring the whole page
 * (and every expansion pack) is a one-line change to --accent in style.css.
 *
 * Already in /style.css (intentionally NOT duplicated):
 *   :root tokens, html/body/a/button resets, ::selection, .mono, .wrap,
 *   .btn / .btn.primary / .btn.outline / .btn.ghost / .btn .arrow,
 *   .section, .reveal, .sblock.warm overrides.
 *
 * --pack-hue chain:
 *   main { --pack-hue: var(--accent); }     ← set below
 *     .pkhero-bg, .pkhero h1 em, .btn.primary, .btn.outline, .pkhero-art,
 *     .pack-name, .wave-strip, .pkhero-stats .num em, .sec-head h2 em,
 *     .scene:hover, .buy-box (border tint),
 *     ::selection
