Challenge

Given an integer n (where 4<=n<=10**6) 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 as long as it's permitted by standard I/O rules.
  • 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.
  • Output may not contain any trailing spaces but a trailing newline is permitted if absolutely necessary.
  • This is so lowest byte count wins.
