/**
 * Graded Card Modal — Newtype v2 chrome
 *
 * The modal shell (overlay, container, header, body, footer, form, view
 * details) is on the v2 HUD vocabulary: dark fill, neon border with
 * angular clip-path corners + brackets, mono uppercase labels, neon-glow
 * focus rings, HUD action buttons.
 *
 * The slab visualization (`.slab`, `.slab-header`, `.slab-card-window`,
 * `.slab-psa/.slab-bgs/...`) is INTENTIONALLY left in its pictorial,
 * glossy-plastic form. It's a representation of a physical graded card
 * slab, not chrome, so it does not adopt v2 styling.

/* `.hidden` is defined as the canonical utility in styles/utilities/display.css.
   Do not redeclare it here — when this file loads later in the cascade (e.g.
   under the deferred-CSS block in index.html), a local `.hidden` would override
   `.modal-open` and prevent any modal that opens by adding `.modal-open` to an
   element that still carries `.hidden`. See PR fixing PR #832 regression. */
