"""Generate the age anchor portraits for every character of a lifeline.

Base portrait: text-only (children optionally with the parents as references).
|
|
Each further anchor: references = base portrait + previous anchor, so identity
|
|
stays pinned to the base while aging progresses step by step.

Existing files are kept; delete a file to regenerate it.
