chore: Initialize backlog with project roadmap tasks 

6 tasks tracking the full build pipeline:
1. Initial design (Done) — OpenSCAD, firmware, schematic
2. Breadboard POC — test IR LEDs vs cameras
3. 3D print prototype frame
4. Flex PCB strip design and fabrication
5. ATtiny85 firmware flash + system integration
6. Camera defeat testing and optimization

## Description
<!-- SECTION:DESCRIPTION:BEGIN -->
Created parametric OpenSCAD models (stealth integrated frame + snap-on clip), ATtiny85 PWM firmware, SVG circuit schematic, and rendered 10 preview images. Stealth design uses flush-mounted SMD IR LEDs behind IR-pass filter strips.

## Description
<!-- SECTION:DESCRIPTION:BEGIN -->
Order components (SMD IR LEDs, IRLML6344 MOSFETs, ATtiny85, TP4056 charger, LiPo battery) and breadboard a minimal circuit with 4 LEDs. Test against iPhone, Android, laptop webcam, and USB security camera to verify bloom/whiteout effect at 940nm. Measure effective range and daylight performance.
<!-- SECTION:DESCRIPTION:END -->
## Acceptance Criteria
<!-- AC:BEGIN -->
- [ ] #1 Components ordered from LCSC/Mouser
- [ ] #2 4-LED breadboard circuit working
- [ ] #3 Tested against 3+ camera types
- [ ] #4 Effective range documented
- [ ] #5 Daylight vs indoor performance compared

## Description
<!-- SECTION:DESCRIPTION:BEGIN -->
Print the integrated frame from integrated_frame.scad in PETG matte black. Verify LED channel dimensions, filter slot fit, temple wire routing, battery cavity, and hinge mechanism. Test-fit IR filter strip (cut from Wratten 87C gel sheet). Adjust parametric dimensions as needed.
<!-- SECTION:DESCRIPTION:END -->
## Acceptance Criteria
<!-- AC:BEGIN -->
- [ ] #1 Frame printed in PETG, no warping
- [ ] #2 IR filter strip press-fits into brow bar slot
- [ ] #3 Flex PCB strip slides into channel cleanly
- [ ] #4 Battery fits in temple tip cavity
- [ ] #5 Charge port accessible from underside

## Description
<!-- SECTION:DESCRIPTION:BEGIN -->
Design a thin flex PCB strip (4mm wide, ~100mm long) with 8x SMD IR LED footprints (PLCC-2/3528), current limiting resistors, and a connector tail. Use KiCad for PCB layout. Order from JLCPCB flex PCB service. Solder SMD components.
<!-- SECTION:DESCRIPTION:END -->
## Acceptance Criteria
<!-- AC:BEGIN -->
- [ ] #1 KiCad PCB layout complete
- [ ] #2 Design rule check passes
- [ ] #3 Flex PCB ordered from JLCPCB
- [ ] #4 SMD LEDs and resistors soldered
- [ ] #5 Strip fits inside frame brow bar channel

## Description
<!-- SECTION:DESCRIPTION:BEGIN -->
Flash zk_glasses.ino onto ATtiny85 via USBasp programmer. Wire complete circuit: MCU → MOSFETs → flex PCB LED strips → battery → charger → switches. Assemble into printed frame. Test all 6 modes, brightness control, button response, battery life, and USB-C charging.
<!-- SECTION:DESCRIPTION:END -->
## Acceptance Criteria
<!-- AC:BEGIN -->
- [ ] #1 ATtiny85 flashed and running
- [ ] #2 All 6 LED modes working
- [ ] #3 Button short/long/double press working
- [ ] #4 Battery charges via USB-C
- [ ] #5 Status LED shows low battery warning
- [ ] #6 Full assembly fits in printed frame

## Description
<!-- SECTION:DESCRIPTION:BEGIN -->
Systematic testing against facial recognition systems. Test against OpenCV/dlib face detector, cloud FR APIs (AWS Rekognition, Google Vision). Measure at various distances (1-5m), lighting conditions (indoor, outdoor, night), and camera types (phone, webcam, CCTV, doorbell). Optimize LED angle, brightness, and pulse frequency for maximum disruption with minimum power draw.
<!-- SECTION:DESCRIPTION:END -->
## Acceptance Criteria
<!-- AC:BEGIN -->
- [ ] #1 Face detection fails at 2m+ indoor
- [ ] #2 Tested against 3+ FR algorithms
- [ ] #3 Optimal pulse frequency identified
- [ ] #4 Power vs effectiveness tradeoff documented
- [ ] #5 Limitations documented (daylight, high-end cameras)
