Let's draw the Triforce

Question

The Triforce is a fictional artifact in The Legend of Zelda, made of three identical-looking equilateral triangles representing power, wisdom and courage. Several games in the saga include an animation when the three parts finally join together.

The purpose of this challenge is to draw a single 2D frame of such a simplified animation, with a given width for the triangles and a given spacing between the parts.

Input

The input consists of two integers: a width \$w\ge1\$ and a spacing value \$s\ge0\$.

Output

The frame has to be drawn according to the following specifications:

         /\
        /  \____________ this part is horizontally centered
       /    \
      /______\
                    \___ s empty lines
                    /
   /\          /\
  /  \        /  \______ w+1 backslashes
 /    \      /    \
/______\    /______\
                \_______ 2w underscores
        |__|
          \_____________ 2s spaces

In the above example, we have \$w=3\$ and \$s=2\$.

More examples

\$w=1\$, \$s=0\$:

   /\   
  /__\  
 /\  /\ 
/__\/__\

\$w=2\$, \$s=0\$:

     /\     
    /  \    
   /____\   
  /\    /\  
 /  \  /  \ 
/____\/____\

\$w=3\$, \$s=3\$:

          /\          
         /  \         
        /    \        
       /______\       



   /\            /\   
  /  \          /  \  
 /    \        /    \ 
/______\      /______\

\$w=4\$, \$s=1\$:

          /\          
         /  \         
        /    \        
       /      \       
      /________\      

    /\          /\    
   /  \        /  \   
  /    \      /    \  
 /      \    /      \ 
/________\  /________\

Rules

• Trailing spaces on each line are optional.
• Extra leading spaces on each line are not allowed.
• You may output a single extra leading newline and/or a single extra trailing newline.
• This is code-golf.

＋├：⁸╵＼Ｌ_×；∔║ω╋║↕

Try it here!

Explanation:

+├                s + w + 2
  :               duplicated (for both X & Y)
   ⁸╵\            w+1 sized diagonal
      L_×         "_"*width of the diagonal
         ;∔       prepended before the diagonal
           ║      palindromize that
            ω     and push the argument of ║ (aka the unpalindromized version)
             ╋    overlap the upside down half-triangle over the upside down triangle at (s+w+2; s+w+2)
              ║   and palindromize the whole thing
               ↕  reverse everything vertically

note: in the making of this I fixed a mistake in the code, Without that fix, this would be 18 bytes.
