<# .SYNOPSIS Smushes two lines of text vertically based on specified smushing rules. .DESCRIPTION This function takes two lines of text (`line1` and `line2`) and combines them vertically by applying vertical smushing rules. The smushing behavior is determined by the `vLayout` and individual smushing rules (`vRule1` to `vRule5`) provided in the `opts` parameter. If no valid smushing rule applies, the characters from both lines are retained as-is. .PARAMETER line1 The first line of text to smush. .PARAMETER line2 The second line of text to smush. .PARAMETER opts A hashtable containing smushing options, including: - `fittingRules.vLayout`: Specifies the vertical layout type (e.g., Fitted, UniversalSmushing). - `fittingRules.vRule1` to `vRule5`: Boolean flags indicating which smushing rules to apply. .EXAMPLE $line1 = "Hello" $line2 = "World" $opts = @{ fittingRules = @{ vLayout = [LayoutType]::UniversalSmushing vRule1 = $true vRule2 = $false vRule3 = $true vRule4 = $false vRule5 = $true } } $result = Vertically-SmushLines -line1 $line1 -line2 $line2 -opts $opts This example smushes the lines "Hello" and "World" using UniversalSmushing and the specified smushing rules. .NOTES This function relies on helper functions (`Uni-Smush`, `vRule1-Smush`, `vRule2-Smush`, `vRule3-Smush`, `vRule4-Smush`, and `vRule5-Smush`) to evaluate individual character pairs for smushing.
