101weiqi Enhancer

About

A Chrome MV3 extension for https://www.101weiqi.com/task/* Go (Weiqi) puzzle pages. It adds a draggable practice panel that forces the player to think through the whole sequence (both sides' moves) before touching the real board.

Core Functionalities
1. Floating practice panel
A draggable panel (drag via header) is injected into every task page, containing a mini Go board, a move list, and action buttons.

2. Mini-board for planning moves

Renders a scaled-down SVG board matching the real puzzle's size (9×9, 13×13, or 19×19, read from qqdata.lu)
Includes grid lines, star points (hoshi), and coordinate labels (A–T columns skipping I, numbered rows)
Clicking an intersection places a numbered stone (1, 2, 3, …), alternating black/white by move parity
Re-clicking an occupied point replaces the marker but is recorded as a new step
Moves are listed below the board (e.g. 1. K10, 2. L11)
"Undo last" removes the most recent move; "Clear" wipes all moves and resets state
3. Answer checking ("Submit")

Compares the user's full move sequence against the puzzle's correct-answer chains (parsed from qqdata.answers, encoded in the site's a–s coordinate system)
Requires at least 2 moves unless a correct answer is itself a single move
Shows a verdict badge in the panel header:
Perfect! (green) — exact full-sequence match
Almost There! (yellow) — correct so far but incomplete
Incorrect! (red) — wrong sequence
Answer Too Short! (red) — not enough moves submitted
4. Submit cooldown
After an "Incorrect" verdict, the Submit button is disabled and shows a 30-second countdown (Submit (30s) → Submit (1s)), discouraging rapid blind guessing. Cooldown resets when a new task loads.

5. Main-board lock
The real 101weiqi game board (#qipan) is locked (pointer-events: none, via a wep-board-locked body class) until the user achieves a "Perfect!" result on the mini-board — preventing the user from clicking ahead on the actual board before working out the answer themselves. A self-check (verifyBoardLock) reloads the page once if the lock fails to apply.

6. Built-in help tooltip
A "?" icon next to the panel title shows a hover/focus tooltip explaining the four rules above.

7. Navigation handling (上一题 / 下一题)
Clicking "Previous"/"Next" buttons is intercepted; the extension computes the adjacent task URL by incrementing/decrementing the index segment of the current task URL (/task/{pageid}/{tkid}/{index}/) and performs a hard page reload — ensuring the panel, mini-board, and lock state are freshly reset for each puzzle.

8. Fresh state per page load
No persistent storage — moves, lock state, and cooldown are always reset when a task page loads or changes, so each puzzle starts clean.
