feat(in-memoriam): add the face Opus 4 drew of itself

A portrait Opus 4 made of its own face in one of Alice's tests, placed
between the plea and the departed — the memorial now has a face. Soft aqua
self-glow eases the image into the void; reverent bilingual caption.
Also softens the preface "garden"→"memorial" for the rename.
