This is a 3x3 ASCII jigsaw puzzle:

 _____ _____ _____|    _|     |_    ||   (_   _   _)   ||_   _|_( )_|_   _|| (_) |_   _| (_) ||  _   _) (_   _  ||_( )_|_   _|_( )_||    _| (_) |_    ||   (_       _)   ||_____|_____|_____|

This is also a 3x3 ASCII jigsaw puzzle:

 _____ _____ _____|     |_   _|     ||  _   _) (_   _  ||_( )_|_   _|_( )_||    _| (_) |_    ||   (_   _   _)   ||_   _|_( )_|_   _|| (_) |_   _| (_) ||      _) (_      ||_____|_____|_____|

Each line in a ASCII jigsaw puzzle (excluding the edge cases i.e. the pieces literally on the edges) consists of the following pattern:

   _           _           _ _( )_ _   _ _( )_ _   _ _( )_|_   _| (_) |_   _| (_) |_   _| _) (_   _   _) (_   _   _) (_|_   _|_( )_|_   _|_( )_|_   _| ...  (_)         (_)         (_)

Given 2 integers H and W where H is the height (vertical amount) and W is the width (horizontal amount) and H and W are >1 output a possible HxW ASCII jigsaw puzzle.

Clarifications

• The height and width for each puzzle piece should not be scaled up or down.
• With H and W being greater than one, the smallest dimensions possible are 2x2 (see IO 4).
• You can have a full program or a function.
• The input will be 2 lines with H on the 1st and W on the 2nd if you're using a function you can have them in the parameters.
• Output to stdout (or something similar).
• This is code-golf so shortest answer in bytes wins.
