# Srijika: OpenType-Layout-Reusing Font Restyling for Nine Indic Scripts

## One-sentence takeaway

Srijika restyles glyph *outlines* from shaping-complete OpenType template fonts while preserving cmap/GSUB closure and GPOS under a documented metric policy — so complex-script shaping keeps working after a visual restyle.

## Why it matters here

Slug 1128 taught GPU outline rasterization; UAX #9 1599 covers bidi. The leftover for GRID COMMAND / Anoptic UI is *OpenType layout reuse*: Indic and other complex scripts die when you regenerate glyphs without the GSUB/GPOS graph. Srijika is the practical recipe — restyle outlines, keep the shaping tables — not another neural font GAN.

## Key ideas

- **Templates are shaping-complete.** Start from fonts that already shape nine Brahmic scripts (Devanagari, Tamil, Bengali, Telugu, Kannada, Malayalam, Gujarati, Gurmukhi, Odia).
- **Preserve layout, replace paint.** Keep cmap and GSUB closure; carry GPOS under an explicit metric policy so kerning/mark attachment survive restyling.
- **Installable OpenType output.** Result is a real font, not a raster atlas — composable with HarfBuzz / system shapers and with Slug-style GPU outline paths.
- **Why not remint Slug.** Slug is rasterization; Srijika is shaping-preserving restyle — orthogonal leftover of the Unicode/text shelf.

## Caveats

arXiv `2609.05661` (cs.CV/cs.GR, Sep 2026); no DOI at harvest. Focused on Indic Brahmic scripts — validate for CJK/Arabic before treating as universal. Do not remint Slug 1128 or UAX #9 1599. Skip GlyphAnchor / neural font priors (cite-not-mint).
