New agents now get a blobatar — a deterministic soft-body face generated
from the bot's name (same name, same face, forever) — as the default
shapes mode, with full manual control:
- Face follows the name live while typing in New Agent
- Randomize re-rolls the seed; Lock face pins the current one so a later
rename can't change it (Unlock returns to name-following)
- Any of the six silhouettes (round/organic/boxy/nub/cloud/sun) can be
pinned via frozen-per-major trait positions while the rest stays
name-derived
- Classic geometric shapes remain one click away, and existing bots keep
their stored looks untouched
Wiring: blobatar@0.2.0 (zero deps, ~3.7KB) exported through the plugin
SDK (blobatarSvg / Blobatar), feature-detected in plugin.js with a
legacy-shape fallback for older desktops. Blob shape strings are
'blobatar[:seed[:kind]]' inside the existing meta.shape field, so
persistence, cross-machine ui_meta sync, and the roster's PNG backfill
(data-bot-face tag preserved) all work unchanged.
