Difficulty ensuring workflow stability and providing user guidance within AppMode

### What problem are you experiencing?

The current AppMode implementation lacks the necessary constraints and documentation layers to make workflows "production-ready" for non-technical users or artists.

Specifically:
- Lack of Input Validation: Without the ability to define boundaries (Min/Max/Step), it is very easy for a user to input values that cause the generation to fail, produce artifacts, or exceed hardware VRAM limits (e.g., setting latent dimensions too high or CFG values to extremes).
- Lack of Contextual Guidance: Complex workflows often have specific parameters that require explanation. Without a space for a high-level description or per-parameter tooltips, users are forced to refer back to external documentation or the original node graph to understand the intended use of a field.

### When does this problem occur?

This issue occurs whenever a "Power User" or "Workflow Builder" prepares a tool for a "Creative User":
- During Handoff: When an artist opens the AppMode interface and is presented with a "Seed" or "Scale" slider without knowing the safe operational range.
- Onboarding: When a new user tries to use a specific AppMode template and doesn't understand the nuance between two similar-looking text fields (e.g., "Main Prompt" vs. "Style Modifier").

### How often do you encounter this problem?

Several times per week

### How much does this problem affect your workflow?

Blocks me from completing tasks

### Current workarounds

Currently, I'm not using the native AppMode for production environments at all. Instead, I have had to build and maintain a completely separate, custom frontend for artists, that supports these fundamental features (ranges and tooltips). This creates a fragmented experience where I cannot take full advantage of the official ComfyUI AppBuilder ecosystem because it doesn't yet provide the "guardrails" necessary to keep workflows from breaking during creative sessions.
