No settings icon exists in the game art (mainfolderimages holds only
copy/del/select-arrow/X/check/dot), so a miniature slider control is drawn
instead: three menu-box tracks with offset knobs in the 14px gap after Erase
(10px wide, 2px margins), INK_DIM tracks, knobs matching the label ink
(white / gold while hot). Tracks the dynamic label x (JP-safe), text position
unchanged; hot region extended to include the glyph. PCDUMP pixel-verified.
