Generate a complete, compilable SwiftUI animation file in the legendary-Animo style. No placeholders. No TODO comments.

## When to Use
- Building a SwiftUI button, gesture, slider, or liquid effect with premium physics
- Need haptic feedback timed correctly to animation phases
- Creating a drag interaction with resistance, snap, or threshold trigger
- Animating SF Symbols with draw-on, breathe, bounce, replace, or variable color effects (iOS 17–26)
- Building a Canvas loader that traces a shape outline with a comet trail (infinity, star, polygon…)
- Morphing a flat grid of elements into a faux-3D spinning form (drum, globe, helix) and back
- Building a card-reveal pack (swipe-to-tear, 3D card flip, staggered stat fills) or Canvas power-effect showcase
- Building an onboarding spotlight tour / coach marks that walk the user across real controls (dim scrim, cutout, pointing tooltip)
- Editing an existing SwiftUI animation file

## Scope & Safety
- Writes only inside the user's current project: the new or edited `.swift` (or `.metal`) file and, when needed, that project's `project.pbxproj`. Nothing outside the working directory.
- No network access, no package installs, no shell scripts. In Edit mode, only the named file changes.

## Mode Detection
- **Edit mode**: prompt contains "edit", "update", "add X to", "change", or a `.swift` filename → read file first, change only what's asked, overwrite file on disk
- **Create mode**: everything else → generate a new complete file and write it to disk

## Intent Inference (runs before code generation)

Before generating any code, parse the prompt for under-specified details and resolve them to defaults. Print a `🔍 Inferred from prompt:` block so the user can see — and override — what was auto-resolved. Only print lines that were actually inferred (not ones the user explicitly stated).

### Step 0 — Normalize designer vocabulary

Translate any designer words in the prompt into skill-understood terms before running subsequent steps. This lets non-technical prompts ("snappy card that rips with anticipation") produce the same output as fully specified ones.

**Animation feel words → physics preset:**

| Designer says | Maps to |
|---|---|
| snappy / crisp / tight | UI pop `0.35/0.6` |
| bouncy / springy / elastic | Snap `0.35/0.5` |
| stretchy / rubber / wobbly | 3-phase rubber-band (see iOS 26 section) |
| melts / floats / soft / gentle | Slow morph `0.6/0.8` |
| stiff / precise / mechanical | Precision stiff `interpolatingSpring(220, 22)` |
