   ZARIIA — shared page language.  Rev. 26 July 2026 (2): THE REGISTERED
   VESSEL.

   ── Where this comes from ──────────────────────────────────────────────
   Four sources, and they are one idea. A Greek amphora, a Kutchi pot, a
   Moroccan lantern and a matryoshka are all VESSELS CARRYING BANDED
   DECORATION, and each of them either opens or lets light through.

     · GREEK POTTERY  — the body divided into horizontal REGISTERS, each
       band a separate field, separated by a MEANDER (the Greek key). The
       key is drawn as ornament here, which is not a pun the project needs
       to explain: it is what the ornament has always been called.
     · KUTCHI EARTHENWARE — fired clay body with fine BONE-SLIP lines and
       dotted bands laid over it. The wheel's horizontal trace is left
       visible in the ground. Terracotta is the body, not an accent.
     · MOROCCAN — light arriving THROUGH A PIERCED SCREEN, so illumination
       is a pattern of points rather than a wash; and the zellij eight-
       point star as the section marker.
     · MATRYOSHKA — NESTING. Sealed matter is drawn as a frame inside a
       frame inside a frame, the innermost unlit. One thing inside another
       is the object this label makes.

   ── The device ─────────────────────────────────────────────────────────
   The page is read as a fired vessel: horizontal registers on a clay
   ground, ruled apart by meander bands, lit through a pierced screen,
   with the sealed channel shown as a nesting rather than as a panel.
   (Replaces the previous "lit aperture" pass, which read as a generic
   dark page — Prayas: "does not have its own look enough".)

   ── The chord moved, and this is a brand decision ──────────────────────
   Away from indigo-night-as-dominant, toward a FIRED EARTHENWARE BODY:
   black-slip dark, terracotta, bone slip, struck gold, with the Moroccan
   blue-teal as the cold counter-voice. The meanings are unchanged —
   gold = the open song, terracotta/ember = the sealed channel alight,
   teal = the cold latent state. `../brand/brand.md` needs updating to
   match; flagged, not done silently.
   Type: Antic Didone (display AND prose) / Cutive Mono (machinery only).
