/* Internal Jeet Service ($IRS). Form J-1040, printed by a machine whose counter has overflowed.
   The page is ONE SHEET on the dark screen of the machine that printed it. Its grammar comes from the
   reference photograph (NOTE.md > Reference teardown): one dominant ink, a double rule with rounded
   elbows, a dot run between the rules, a dark band with two numerals at the top, a readable left
   region against a dense corrupted region at 50..73% of the width, and one strip that carries all
   the colour.

   Rewritten 2026-11-02 to the owner's review:
   ONE TYPE SCALE   16 / 20 / 24 / 32 / 48, and nothing else. His list starts at 12, but the kit's
                    floor is 16 px for anything a visitor reads (RULES/05_TYPE_AND_SURFACES.md), so
                    the scale is his with the bottom two steps dropped instead of used.
   ONE SPACE SCALE  4 / 8 / 12 / 16 / 24 / 32 / 48, and nothing else.
   ONE FACE A ROLE  Public Sans for headings and paragraphs, Overpass Mono for values, addresses and
                    the small print, Press Start 2P for the form's own code in the masthead and
                    nowhere else. */
