Titan Combat: Frontline Mechs

### Cockpit & HUD
- Real first-person cockpit: canopy frame, instrument panel and the titan's own arms/weapon rendered around the camera, animated for firing, melee and walking.
- New Titanfall-style HUD: boot sequence on embark, compass, radar, hull/shield bars, dash cells, core meter, per-weapon reticles, critical alerts.
- Boarding sequence: summoned titans kneel with the hatch open; boarding seals the hatch and the titan stands up.
- Redesigned Cockpit Bay (E) with a live 3D titan preview and weapon/munitions/reactor/cargo slots.

### Weapons
- 7 weapon modules that fit any chassis. Titans start unarmed.
- Per-weapon magazines and ammo, reload [R], raise-before-fire (Predator spin-up), lower weapon [H].
- Hull plating vs. infantry guns (TACZ / Superb Warfare): small arms mostly ricochet; explosives and titan weapons hurt. The pilot is protected inside.
- Defense Matrix shows a blue energy dome.

### Movement
- Footsteps synced to the animation's foot plants, with dust and screen shake.
- Stride-matched ground speed (no foot sliding or sinking), inertia, sprint.
- 3 dash charges + jump jets with thruster effects.
- Torso follows aim, legs turn after it, lean into acceleration and turns.
- Smooth step-up/down and foot placement on uneven ground.
- Melee with wind-up and impact timing; Ronin sword combos.

### Eject
- Press [X] twice (once when critically damaged): the hatch blows, the pilot rockets skyward and slow-falls to safety, and the titan self-destructs 2.5 s later.

### Items
- All items redrawn as 32x32 pixel art, plus 7 weapon modules and 7 magazine types.

### Fixes
- Crossed arms while kneeling, frozen animations after parking, duplicate guns, bullet drop missing the reticle, pilot floating outside the cockpit, Z key repeat.
