Indic Positional Category - Top And Left And Right

Top And Left And Right is a value that indicates a vowel sign or dependent mark is positioned above, to the left, and to the right of the base consonant, typically forming a three-sided enclosure or wraparound shape. This occurs in certain Indic scripts where a matra extends both before and after the consonant while also rising above it, as seen in some combinations of vowels or when a pre-base form interacts with an upper diacritic. The value specifically captures this triple spatial alignment, distinguishing it from simpler placements like top-only or left-right, and helps shape rendering for correct visual stacking and reordering during text shaping.
