Add 4 example circuits accessible from a new toolbar dropdown:
- SR Flip-Flop (NOR) — basic set-reset latch
- SR Flip-Flop (NAND) — active-low variant
- D Latch (1-bit Memory) — gated latch with enable
- D Flip-Flop (Master-Slave) — edge-triggered with CLK
Each example shows name + description in the dropdown and loads
the full circuit with proper gate placement and wiring.

Replace horizontal toolbar sections with dropdown buttons (I/O, Gates,
Components). Each opens a dropdown menu on click, keeping the toolbar
clean and compact. Dropdowns close on outside click or after selecting
a gate.

Redesign toolbar sections to use horizontal button rows instead of
vertical stacking. Fix component placement by attaching click handlers
directly to dynamically created buttons and passing correct gate object
shape to getComponentWidth/Height.

- Redesigned toolbar with I/O, Gates, and Components sections
- Component editor: sub-canvas mode to design reusable chips
- Save/Cancel with main circuit state preservation
- Components persist in localStorage
- Custom components render as purple chips with dynamic I/O ports
- Component evaluation simulates internal circuit as black box
- Toolbar height increased to 56px for section labels
- All height references updated consistently

- Puzzle panel now shifts canvas and waveform viewer right (340px) instead of
overlapping them, using body class toggle and CSS transitions
- Canvas resize accounts for sidebar width
- Progress (completed/unlocked levels, custom components) persists in localStorage
- Level cards refresh on each panel open to reflect current progress

Add progressive puzzle mode alongside the existing sandbox:
- 8 levels from basic gates to 2-bit adder
- Truth table verification with pass/fail feedback
- Gate restrictions per level
- Custom components system (save circuits as reusable chips)
- Save/load circuits as JSON
- Level selection sidebar with difficulty ratings
- Mode toggle: Sandbox (free play) vs Puzzle (guided levels)
