/**
 * Core Download Plugin v2 — Download Card
 *
 * Utilitarian precision (Swiss-influenced): hairline rules carry structure,
 * one restrained cobalt accent on the primary action + focus + links only,
 * a strong but honest type ramp, near-flat surfaces. Every color/size/
 * duration below is a `--cdp-*` token from tokens.css — dark mode and
 * owner-tuned accent/radius/font follow automatically; nothing here is
 * re-declared for `[data-cdp-theme="dark"]`.
 *
 * Layout responds to its own box, not the viewport (`container-type:
 * inline-size` on the card root) so it holds up in a 280px sidebar column
 * exactly as well as a full-width content area. See the breakpoint
 * reference at the bottom of tokens.css: the one card breakpoint is 480px,
 * below which per-file meta stacks under the filename and the gated-form
 * fields stack vertically.
