+Act as an experienced Senior Fullstack/Linux Developer. Write a robust Python 3.10+ program to capture images from an RTSP home camera for a professional-grade time-lapse of a fern growing over 30-40 days.
+
+**Project Context & Strategy:**
+- To ensure consistent lighting and minimize "shadow flicker," frames will be captured only during a 6-hour window daily (e.g., 10:00 AM - 4:00 PM).
+- Interval: Capture one frame every 10 minutes.
+- Target: ~36 frames/day, resulting in ~1440 frames over 40 days (~48 seconds of video at 30 FPS).
+
+**Core Requirements:**
+1. **Target Platform:** Linux.
+2. **Capture Engine:** Use `ffmpeg` via Python `subprocess`. 
+   - *Technical Note:* If possible, suggest/implement flags to lock or stabilize auto-exposure/white balance to prevent color flickering between frames.
+3. **Execution Logic:**
+   - The script should check the current system time. It must only capture and save a frame if the time falls within the predefined "Golden Window" (e.g., 10:00 - 16:00).
+   - Alternatively, design the script to take a single frame and exit, so it can be triggered by a `cron` job.
+4. **Resilience:**
+   - Implement robust error handling for RTSP stream timeouts or network drops.
+   - Use exponential backoff for retries.
+   - Log all activities (success, skips, errors) to a local file.
+5. **Output Management:**
+   - Save high-quality JPEGs to a structured directory.
+   - Filename format: `YYYY-MM-DD_HH-MM-SS_ferngrowth.jpg`.
+6. **Video Compilation:**
+   - Provide a separate function or command to compile the final `.mp4` using `ffmpeg` at 30 FPS. Use high-quality libx264 settings.
+
+**Strict Coding Guidelines:**
+- Clean, modular code (SOLID/DRY).
+- Use modern Python 3.10+ (type hinting, logging).
+- **Do not use Polish diacritics in code comments.**
+- If any C/C++ is used, follow LLVM brace style.
+- Provide a brief summary of "What" and "Why" regarding the architecture.
+- Include a sample `crontab` entry to automate the 10-minute interval during the 6-hour daily window.
