=head1 DESCRIPTION
C<PDF::Make::Redaction> provides a two-step redaction workflow following PDF
specification conventions:
=over 4
=item 1. B<Mark> - Define rectangular areas to be redacted, with optional
overlay text and color.
=item 2. B<Apply> - Burn the redaction overlays into the content stream,
permanently removing the underlying content.
=back
A separate C<sanitize> step removes document-level metadata (title, author,
subject, etc.) from the Info dictionary.
=head1 CLASS METHODS
All methods are class methods called on C<PDF::Make::Redaction>.
=head2 mark($page, %args)
PDF::Make::Redaction->mark($page,
rect => [x0, y0, x1, y1], # or use x0/y0/x1/y1
overlay_color => [0, 0, 0], # RGB, default black
overlay_text => 'REDACTED', # optional text overlay
overlay_font_size => 10, # default 10pt
);
Mark a rectangular area on C<$page> for redaction.
=over 4
=item C<rect> - ArrayRef of [x0, y0, x1, y1] in PDF coordinates
=item C<x0, y0, x1, y1> - Alternative: specify corners individually
=item C<overlay_color> - RGB color array for the redaction box (default [0,0,0])
=item C<overlay_text> - Text to display over the redacted area
=item C<overlay_font_size> - Font size for overlay text (default 10)
=back
=head2 count($page)
my $n = PDF::Make::Redaction->count($page);
Returns the number of redaction marks on the given page.
=head2 apply_page($page)
PDF::Make::Redaction->apply_page($page);
Apply all redaction marks on a single page, burning overlays into the
content stream. Croaks on failure.
=head2 apply_doc($doc)
PDF::Make::Redaction->apply_doc($doc);
Apply all redaction marks across every page in the document. Croaks on
failure.
