What this changes

Adds I9kNinoMaze, 9k.school's 404 maze game rebuilt in the design system's language, so 9k.school, ismail9k.com and the9klabs.com can share one 404 game.

• Seeded random mazes: every seed builds one maze, and the same seed always builds the same maze. Each maze is checked to be winnable before it is shown, by a search over (tile, turn) that is cross-checked against an independent solver in the tests. There are three difficulties: easy (11×9, 1 bug), normal (15×11, 2) and hard (21×13, 3).
• Bar: shows a shareable maze code (Maze #1CBWUUF), the move count, a New maze button (dice) and a mute toggle (aria-pressed).
• Controls: arrow keys, W A S D (also read by physical key, so they work on an Arabic layout), and an on-screen d-pad that stays left-to-right on RTL pages.
• Chiptune sound moved from 9k.school: no audio before the visitor interacts, and a muted game never creates an AudioContext.
• Localization: every string can be replaced through labels; counted messages are functions so they plug into i18n.
• Server rendering: with no seed, the server renders an empty board with aria-busy and the client picks a seed on mount, so there is no hydration mismatch.
• Public API: exports I9kNinoMaze, its types, and formatI9kNinoMazeSeed / parseI9kNinoMazeSeed. Also adds a showcase entry, a Storybook story, and five icons (arrowLeft, arrowRight, dice, volumeOn, volumeOff).

Verification

• npm run check passes: 1079 tests, format, lint, typecheck, library build, Storybook build, showcase prerender.
• Checked in Storybook: light and dark themes; the Arabic page (the bar mirrors, the d-pad does not); Hard at 375px with no horizontal scroll; a full keyboard win (status, disabled d-pad, Play again / New maze).
• A fresh whole-branch review found no critical issues. One important issue and two findings promoted to important were fixed, each test-first:
  • focus is no longer lost on a d-pad win;
  • W A S D now work on non-Latin layouts;
  • a label passed as undefined no longer crashes the component.

Known minor follow-ups:

• A second "wall" announcement in a row is not re-announced.
• The component looks wrong inside I9kSection variant="primary".
• Hard-maze generation is synchronous; up to about 60ms on a dev machine.
