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 code-golf so lowest byte count wins.

_{* Yes, I'm aware that the bigger it gets the less it looks like a prison door! :D}
