/* ARMA GROUP — CERTIFICATE VIEWER
 * ---------------------------------------------------------------------------
 * Structure, rhythm and behaviour for the certification register. Carries no
 * palette of its own: every colour resolves from a custom property the host
 * page defines, so the same component reads as ARMA Electric's dark control
 * room, Line Hardware's amber workshop, or Real Estate's paper-and-ink world.
 *
 * Host pages must define, on :root or a wrapping scope:
 *   --cv-bg          page background behind the register
 *   --cv-surface     document card surface
 *   --cv-surface-2   recessed surface (scan mat, fact rows)
 *   --cv-ink         primary text
 *   --cv-ink-2       secondary text
 *   --cv-ink-3       tertiary / label text
 *   --cv-line        hairline border
 *   --cv-accent      the site's accent hue
 *   --cv-accent-ink  text that sits legibly on --cv-accent
 *   --cv-display     display typeface stack
 *   --cv-body        body typeface stack
 *   --cv-label       label / data typeface stack
