Paths-mode unit rendering now always goes through _markup_unit_svg, which fits the font's actual ink bounds (width AND height) to the unit box — correct for all fonts, not just ГОСТ тип А. Added half-height unit toggle: restricts the unit label to the upper half of the panel box (y1 = midpoint at 103.8 mm), keeping it clear of the numeric labels when they visually crowd the unit area.
