hermes(voice): crop Hermes character into orb as a feathered watermark

Browse Source 
The orb watermark was showing the character art as a low-opacity square
box (visible edges) — the earlier screen-blend pass washed it into a glow
that lost the artwork. Reprocess the source into a feathered circle so the
orb crops it (no box) while keeping the character's facial features, paint
it with a normal blend at 0.5 opacity, and size it to fill the orb (inset
7%). Verified by compositing over a simulated orb before shipping.

// FIX 1: the conversation orb's centred watermark is the Hermes CHARACTER
// glyph — the 512px character art, feathered to a circle and luminance-weighted
// to a warm near-white, inlined as a data URI and painted by
// .voice-conversation-orb-mark in atlas-voice.css with mix-blend-mode: screen
// .voice-conversation-orb-mark in atlas-voice.css cropped into the orb by a feathered circle mask (no box; normal blend)
// so the face features glow over the dark orb. A low-opacity, non-animating
// (reduced-motion safe) layer that scales with the orb and reads across every
// state tint. No separate static asset is served for it.
