v2.0.0 — Gaming mode (picker + Minecraft + generic GAME layers)

Adds a dedicated gaming mode (closes #11) and supersedes the v2.0.0-rc1 prototype, re-applied onto current main (was v1.6.0).

Gaming mode (layers 5–7)

Locked layers that strip all home-row-mods / hold-tap / caps_word — WASD, SPACE and modifiers are pure keys.

• Enter: hold mo(SYS|NUM) (left thumb) → tap the right-thumb outer key → GAME? picker. Joystick ↑ = Minecraft, ↓ = generic GAME (FPS/MOBA), center = cancel.
• Chassis: plain WASD/QWER + plain right half for chat; LCTRL (pinky), LSHIFT (left thumb), SPACE on both thumbs, F13 push-to-talk, mo(MEDIA) reachable. Joystick = audio cluster + center Enter.
• Exit/switch: top corners (0 + 12) → exit to BASE (RGB off); top-left pair (0 + 5) → re-pick.
• Indicator: OLED shows MINECRFT / GAME. Per-game RGB underglow shows on battery (suppressed on USB by AUTO_OFF_USB).

The original entry (SYS joystick-center) became the mouse left-click in v1.5.0, so entry moved to a free SYS thumb key; the joystick-mouse is preserved.

Tooling

• Printable PDF now paginates — mise run draw-pdf puts one A4 page per group of layers (LAYERS_PER_PAGE, default 4 → 2 pages) instead of cramming all layers onto one.
