Module messages 

Text overlay (MILK_MSG.INI) state and lifecycle.

Holds the parsed message definitions (MessageDef) and the active list with per-instance lifecycle state. Each tick computes the current fade alpha for every active message and produces a list of MessageRenderInstances the renderer turns into glyph quads.

Trigger surface (keybinds wired in the GUI layer, §15):

• T — cycle through the loaded message slots in INI order.
• Ctrl+Y — clear every active message immediately.

Also exposes a one-shot transient API (show_transient) used by the MPRIS auto-title path: when MPRIS reports a new track title, the engine spawns a temporary message with a synthesised default style (centred, fade-in / sustain / fade-out).

Structs

ActiveMessage 🔒

One live message instance.

MessageManager

Message system: definitions + active instances + cycle cursor.

MessageRenderInstance

Per-frame snapshot of one active message, fed to the renderer. Mirrors a tiny subset of MessageDef — the renderer only needs positioning + size + colour + the current fade alpha.
