/**
* Empirical Verification & Adversarial Stress Tests:
* Batch 3 Parity Gate (Issue #642, #643, #646, #650, #651)
*
* Verifies:
* 1. Font parsing and metric calculations (src/client/ui/font.ts):
* - Narrow characters (', |, i, l, !, .) retain true widths (2-3px) without synthetic min-width 4 clamping.
* - Chinese DC6 typography metrics (lineMultiplier 14, lineAdvance 14, baselineConstant 2).
* - PL2 13-color shift matrices and text formatting codes (ÿc< = #00c800, ÿc4 = gold, all 13 colors).
* - Drop shadow removal (shadow defaults to false, zero unrequested black outline artifacts).
* 2. Cursor state machine (src/client/ui/cursor.ts):
* - Discrete state transitions: POINTING -> OPENING -> OPEN_IDLE -> RELEASE -> POINTING, and CLICK_DOWN.
* - Authentic 5000ms idle timer countdown with 8.8 fixed-point counters and rewind on movement.
* - Fail-fast on missing cursor artwork (zero canvas solid rectangles, reports missing art).
* 3. Adversarial Fuzzing & Differential Oracles:
* - 1,000-iteration random string parsing & width oracle.
* - 1,000-step cursor event & timeline stress simulator.
