Wordle Caesar Shift

Purpose

Compute the Wordle "shift" (a position-aware Caesar cipher) by shifting each letter forward by 6 + its zero-based position. This matches the behavior used in static/tools/ios-shortcut.js and described in content/shifts/_index.md.

Steps

1. Normalize the input word to lowercase ASCII letters.
2. For each character at position i, shift it forward by 6 + i positions in the alphabet (a–z), wrapping around modulo 26.
3. Join the shifted letters into the encoded shift string.

Example

Input: eight

• e (pos 0) → k
• i (pos 1) → p
• g (pos 2) → o
• h (pos 3) → q
• t (pos 4) → d

Output: kpoqd
