colors, error correction level, margin control, and export as PNG (256–2048px)

via the qrcode package.

Add comment style selector (shadcn Select) to wrap generated ASCII art
with language-appropriate comment syntax (// # -- ; /* */ <!-- --> """).
Refactor preview controls to use shadcn ToggleGroup, Tooltip, and Badge.
Alignment is disabled when a comment style is active.
