Features:
- Track attributes that depend on signals (ternary expressions)
- Store element references in globals for reactive attributes
- Re-evaluate and update only changed attributes when signals change
- Similar to reactive conditionals but for attributes
Performance:
- Minimal DOM updates - only changed attributes are updated
- No full re-renders, no virtual DOM diffing
- Direct attribute updates via js_set_attribute
Example:
class_='tab active' if tab_index == 0 else 'tab'
When tab_index changes, only the class attribute updates.
Implementation:
- Collection phase: scan for attributes with signal dependencies
- Render phase: store element references to globals
- Signal update: re-evaluate expression and update attribute
All tests passing (55 passed, 2 skipped)
