A set of ComfyUI custom nodes to control LoRA (Low-Rank Adaptation) strength programmatically during the sampling process.

        LoRA Keyframes - Schedule LoRA strength during sampling

        FORMAT: strength@percent, strength@percent, ...
        - strength: LoRA strength multiplier at this point (0 = off, 1 = normal, 2 = double)
        - percent: when to apply (0.0 = start, 0.5 = middle, 1.0 = end)

        EXAMPLES:
            • "0@0.0, 1@0.5, 0@1.0" → Bell-shaped curve (fade in/out)
            • "0@0.0, 1@0.3" → Fade in and stay on
            • "1@0.0, 0@0.7" → Start strong, then fade out
            • "0@0.2, 1@0.5, 0@0.8" → Active only in middle

        INTERPOLATION MODES:
            • step       → Rectangular jumps (default ComfyUI behavior)
            • linear     → Linear interpolation between keyframes
            • smoothstep → Smooth fade
            • ease_in    → Starts slow, accelerates
            • ease_out   → Starts fast, slows down
            • ease_in_out → Smooth ease in/out

        RESOLUTION:
            - Controls how many intermediate keyframes are generated between your defined keyframes
            - Number of points = resolution + 1
            - Example: resolution = 20 → 21 keyframes at 0%, 5%, 10%, ..., 100%
            - Higher resolution → smoother curve, more granular strength changes
            - Lower resolution → coarser, fewer keyframes, faster processing

        TIP: Use fewer keyframes for smoother sampling (each keyframe adds a tiny delay)
