+name: add-unicode-block
+description: Add a new Unicode script/block to the Terrarum Sans Bitmap font engine.
+---
+# Add Unicode Block
+
+## Required inputs
+
+The user must supply:
+- **Script name** — human-readable name used in constant/function names (e.g. `Ogham`, `LatinExtE`)
+- **TGA filename** — the sprite sheet filename without path (e.g. `ogham_variable.tga`)
+- **Unicode range** — start and end codepoints inclusive (e.g. `U+1680..U+169F`)
+
+If any of these are missing, ask for them before proceeding. Extra directions can be given after Unicode range.
+
+## Step 1 — Determine the next sheet index
+
+Read the sheet index constants from both files to find the current highest index (excluding `SHEET_UNKNOWN = 254`):
+
+- Kotlin: `src/net/torvald/terrarumsansbitmap/gdx/TerrarumSansBitmap.kt` — grep for `internal const val SHEET_`
+- Python: `OTFbuild/sheet_config.py` — grep for `^SHEET_`
+
+The new index = highest existing index + 1.
+
+## Step 2 — Derive identifiers
+
+From the script name, derive:
+- **Kotlin constant**: `SHEET_<UPPER_SNAKE>_VARW` (e.g. `SHEET_OGHAM_VARW`)
+- **Kotlin indexY function**: `<camelCase>IndexY` (e.g. `oghamIndexY`)
+- **Python constant**: same as Kotlin constant
+- **Range start hex**: the lower bound codepoint as a `0x`-prefixed Kotlin/Python literal
+
+## Step 3 — Edit both files
+
+Make all 6 edits. Read each section before editing.
+
+### Kotlin: `src/net/torvald/terrarumsansbitmap/gdx/TerrarumSansBitmap.kt`
+
+**a) Sheet index constant** — find the block of `internal const val SHEET_*` constants (just before `SHEET_UNKNOWN = 254`) and append:
+```kotlin
+internal const val SHEET_<NAME>_VARW = <INDEX>
+```
+
+**b) fileList entry** — find `internal val fileList` array and append before the closing `)`:
+```kotlin
+"<tga_filename>",
+```
+
+**c) codeRange entry** — find `internal val codeRange` array and append before the closing `)`:
+```kotlin
+0x<START>..<0x<END>, // SHEET_<NAME>_VARW
+```
+Use `+` to combine non-contiguous ranges if needed.
+
+**d) getSheetwisePosition when-branch** — find the `when` block that dispatches to indexY functions (just before `else -> ch / 16`) and append:
+```kotlin
+SHEET_<NAME>_VARW -> <camelCase>IndexY(ch)
+```
+
+**e) indexY function** — find the block of private `*IndexY` functions near the bottom of the companion object and append:
+```kotlin
+private fun <camelCase>IndexY(c: CodePoint) = (c - 0x<START>) / 16
+```
+
+### Python: `OTFbuild/sheet_config.py`
+
+**f) Sheet index constant** — find the block of `SHEET_* = <n>` constants (just before `SHEET_UNKNOWN = 254`) and append:
+```python
+SHEET_<NAME>_VARW = <INDEX>
+```
+
+**g) FILE_LIST entry** — find `FILE_LIST = [` array and append before the closing `]`:
+```python
+"<tga_filename>",
+```
+
+**h) CODE_RANGE entry** — find `CODE_RANGE = [` array and append before the closing `]`:
+```python
+list(range(0x<START>, 0x<END+1>)),                                                  # <INDEX>: <ScriptName>
+```
+
+**i) index_y lambda** — find the dict in `get_index_y(sheet_index, c)` (just before `SHEET_HANGUL: lambda: 0`) and append:
+```python
+SHEET_<NAME>_VARW: lambda: (c - 0x<START>) // 16,
+```
+
+## Step 4 — Verify
+
+After all edits, confirm:
+1. The Kotlin constant, fileList, codeRange, when-branch, and indexY function are all present and consistent.
+2. The Python constant, FILE_LIST, CODE_RANGE, and index_y lambda are all present and consistent.
+3. The indices in both files match.
+4. The range end in `CODE_RANGE` is `end + 1` (Python `range` is exclusive).
