/* =====================================================================
   The Collectorium — Static + error pages (v3)
   ---------------------------------------------------------------------
   Two surfaces, one file, because they share a shape: a single centred
   column on an otherwise empty page.

     .sp-prose  — the reading column (privacy, about/FAQ/contact,
                  account deletion). Capped at a readable measure rather
                  than the shell's 1480px, which is a catalogue width, not
                  a prose one.
     .sp-error  — the 404/403/500 composition: translucent glyph, terse
                  heading, one line of body, one primary button.
     .sp-hero   — the iOS app page's pitch.

   These pages carry no cards, so they sit on the themed page background
   and take their colours straight from the tokens.
