VoicebotTheme class final

Theme for the prebuilt UI kit (VoiceButton, ChatPanel, VoicebotLauncher).

Ships sensible defaults; override any field to restyle. The kit is fully replaceable — a merchant can ignore it entirely and build a custom UI on the headless VoicebotSession streams. Pass via the widgets' theme: param, or wrap a subtree in VoicebotThemeProvider to set it once.

Colors default to null and resolve against the ambient Material ColorScheme at build time, so the kit blends with the host app unless you pin explicit colors.
