# Challenge
Given an integer `n>=4` as input create an ASCII art "prison door"* measuring `n-1` characters wide and `n` characters high, using the symbols from the example below.

---
## Example
    ╔╦╗
    ╠╬╣
    ╠╬╣
    ╚╩╝

The characters used are as follows:

    ┌───────────────┬─────────┬───────┐
    │ Position      │ Symbol  │ Char  │
    ├───────────────┼─────────┼───────┤
    │ Top Left      │    ╔    │ 9556  │
    ├───────────────┼─────────┼───────┤
    │ Top           │    ╦    │ 9574  │
    ├───────────────┼─────────┼───────┤
    │ Top Right     │    ╗    │ 9559  │
    ├───────────────┼─────────┼───────┤
    │ Right         │    ╣    │ 9571  │
    ├───────────────┼─────────┼───────┤
    │ Bottom Right  │    ╝    │ 9565  │
    ├───────────────┼─────────┼───────┤
    │ Bottom        │    ╩    │ 9577  │
    ├───────────────┼─────────┼───────┤
    │ Bottom Left   │    ╚    │ 9562  │
    ├───────────────┼─────────┼───────┤
    │ Left          │    ╠    │ 9568  │
    ├───────────────┼─────────┼───────┤
    │ Inner         │    ╬    │ 9580  │
    └───────────────┴─────────┴───────┘

## Rules
- You may take input by any reasonable, convenient means.
- For the purposes of this challenge, in languages where the symbols used to build the "door" are multi-byte characters, they may be counted towards your score as a single byte each.
- All other characters (single- or multi-byte) should be counted as normal.
- You may output an array/list of lines instead of a multi-line string.
- Output may not contain any leading or trailing whitespace other than a trailing newline where absolutely necessary.
- This is <span class="badge is-tag">code-golf</span> so lowest byte count wins.
