/*
 * Page-specific styles for /products/grfx.
 *
 * Port of the design's inline <style> block in `Imaginando GRFX.html`.
 * Same convention as the DLYM / K7D / TKFX / UBRIDGE product pages —
 * the product-detail chrome (.product-nav, .sec-head, .hero, .req-grid,
 * .help-grid…) is duplicated here intentionally. Hoist into
 * /style.css once the relevant block recurs.
 *
 * Already in /style.css (intentionally NOT duplicated):
 *   :root tokens, html/body/a/button resets, ::selection, .mono, .wrap,
 *   .btn / .btn.primary / .btn.ghost / .btn .arrow, .section, .reveal.
 *
 * GRFX-only chrome:
 *   .triangle-vis  — hero/section centrepiece, draggable handle + grain
 *                    particle canvas. JS in /pages/grfx.js.
 *   .press / .pcard — magazine-style 1.4fr+1fr+1fr review grid where
 *                    the first card just gets more horizontal room.
 *                    All three cards share the same surface, type
 *                    scale and quote-mark glyph — no "featured"
 *                    background tint or larger quote on the first
 *                    card. Differs from DLYM/K7D's .rev-grid (3-col
 *                    equal) only in the column ratios.
 *   .artist-quote  — accent-tinted standout quote panel under .press.
 *   .rack          — FX-rack lanes inside one of the engine tiles.
 *   .tri-demo      — 2-col layout that wraps the Harmonic Triangle
 *                    interactive (left = copy + wow table, right = vis).
 *
 * Palette (GRFX is moodier/cinematic vs DLYM/K7D):
 *   --accent   #5fe3d4 (turquoise)
 *   --accent-2 #b48bff (violet, used for grain accents)
