//! Script-aware shaping helpers layered on top of the cmap → GSUB →
//! GPOS pipeline in [`crate::shaper`].
//!
//! - Round 7: [`arabic`] — Unicode joining-class lookup + the
//!   adjacency state machine that picks `Isol` / `Init` / `Medi` /
//!   `Fina` for every character in a run, plus [`arabic_pf`] for the
//!   Arabic Presentation Forms-B translation table.
//! - Round 8: [`indic`] — Devanagari complex-script cluster machine
//!   (cluster boundaries + pre-base matra reorder + reph
//!   identification).
//! - Round 10: [`indic`] now also covers Bengali (U+0980..U+09FF) and
//!   Tamil (U+0B80..U+0BFF). Bengali shares Devanagari's reph rule and
//!   adds two more pre-base matras (U+09C7 / U+09C8); Tamil's cluster
//!   machine omits reph (no superscript RA) and conjunct formation,
//!   keeping only pre-base matra reorder for U+0BC6 / U+0BC7 / U+0BC8.
//! - Round 12: [`indic`] adds three Brahmic non-Indic scripts —
//!   Sinhala (U+0D80..U+0DFF, halant-driven like Indic), Khmer
//!   (U+1780..U+17FF, coeng-based subjoined consonants via U+17D2),
//!   and Thai (U+0E00..U+0E7F, no halant — pre-base vowels are already
//!   in the visual position). The cluster machine still drives all of
//!   them via [`indic::ReorderRules`] (Sinhala / Khmer reorder the
//!   pre-base matras; Thai is a no-op reorder, only segmentation).
//! - Round 13: [`indic`] adds the remaining two Brahmic non-Indic
//!   scripts — Lao (U+0E80..U+0EFF, structural twin of Thai) and
//!   Myanmar / Burmese (U+1000..U+109F, Asat killer + medials +
//!   kinzi reph-equivalent). The [`indic::RephKind`] enum carries the
//!   kinzi pattern (NGA + Asat + Virama + Cons) as a separate variant
//!   so the cluster reorderer dispatches the right reph detector.
//! - Round 15: [`general`] — general-script (`latn` / `cyrl` / `grek` /
//!   `DFLT`) GSUB feature pass. Wires `ccmp` (Glyph Composition /
//!   Decomposition — the OpenType required-feature for any script) as
//!   a pre-ligature pass, and `calt` (Contextual Alternates) as a
//!   post-ligature pass, into [`crate::shaper::shape_run_with_font`].
//!   Dispatches GSUB LookupTypes 1 / 2 / 3 / 4 / 5 / 6 / 8 per the
//!   declared type — previously the pipeline only used types 1 / 4 / 5
//!   / 6 (and only via the per-script Indic / Arabic dispatchers, never
//!   for Latin runs). Type 2 (multiple substitution / decomposition)
//!   becomes reachable for the first time.
