Missing portrait animation

Relevant full-source files in /opt/rise-of-pi/herm-tui:

Key observations:

const compactPortrait = rg40Mode && tab === CHAT_TAB && dims.width < 120 && !(splash && tab === CHAT_TAB)

This explicitly hides the compact portrait while the splash is visible. If the RG appears stuck on the splash, the user never sees the portrait.
