## Summary
Build action take too much time.
Lets see if splitting it to two seperate action would speed things up.

Implements a function to inline <!--#include file="path" --> directives in HTML files. The function resolves includes relative to a base directory and supports up to 8 levels of nesting. Must be called before HTML minification since minification strips comments.
EIGHT_BIT_GRAYSCALE decode of a 3-component progressive JPEG calls
JPEGDecodeMCU_P with MCU_SKIP for Cb and Cr after every Y MCU. The
existing safe-pMCU patch redirects the wild pointer to &sMCUs[0] but
leaves the DC store unguarded, so each chroma skip overwrites the
just-decoded Y DC with the chroma DC predictor. Output reads sMCUs[0],
gets the trailing Cr DC (~0), and renders an all-black image.
Add `if (iMCU >= 0)` guards to the two pMCU[0] writes (main DC store and
successive-approximation update). The pointer redirect stays as the AC
wild-pointer defense; the new guards stop the silent corruption at
sMCUs[0]. The two fixes are independent and both required.
fixes the progressive 8bit grayscale jpeg regression in 1.3.0

## Summary
Relative includes can hide inappropriate dependency relationships. In
this case, I found that lib/KOReaderSync/KOReaderCredentialStore.cpp was
dependent on src/JsonSettingsIO.h -- a lib -> app dependency, the
opposite direction dependencies should flow in this project.
This change replaces all relative includes with root-relative includes,
and corrects the KOReaderCredentialStore dependency by moving its JSON
settings serialization local to the KOReaderSync library.

## Summary
* Rename the hyphenation update script to match the documented
`update_hyphenation.sh` name.
* Update the hyphenation trie documentation command example to use the
renamed script.
## Additional Context
The prose in `docs/hyphenation-trie-format.md` referred to
`update_hyphenation.sh`, but the command example and file on disk used
`update_hypenation.sh`. This made the documented script name
inconsistent with the runnable command.
Verified with `rg` that no references to the misspelled script name
remain. Also ran `bash -n scripts/update_hyphenation.sh` to syntax-check
the renamed script without downloading trie files.
## Summary
Consolidate the script help/startup fixes so standalone helper commands
can show usage without requiring runtime-only dependencies or generating
files.
## Details
Several helper scripts imported optional packages, evaluated newer
annotations, or started generation before users could inspect CLI usage.
On a fresh checkout, this made common help paths fail on missing
packages such as `cairosvg`, `Pillow`, `freetype-py`, `fontTools`,
`pyphen`, `pyserial`, or on Python 3.9 annotation evaluation. A few
generators also treated `--help` as a normal output argument and wrote
files instead of printing usage.
This change keeps runtime dependencies on the code paths that need them,
handles lightweight help/list commands first, and adds explicit `--help`
handling for generator scripts that previously started work.
## Validation
- `python3 <script> --help` across tracked Python scripts, excluding
`scripts/patch_jpegdec.py` because it is a PlatformIO pre-build hook
rather than a standalone CLI
- `python3 scripts/convert_icon.py` still exits with usage for missing
required arguments
- `python3 lib/EpdFont/scripts/fontconvert_sdcard.py --list-presets`
- `python3 -m py_compile` for the changed scripts
## Summary
* **What is the goal of this PR?**
Add end-to-end integrity verification for downloaded font files by
including CRC32 checksums in the font manifest and validating downloaded
`.cpfont` files on device.
* **What changes are included?**
- `generate-font-manifest.py`: compute and include `crc32` for each
`.cpfont` asset in the generated `fonts.json` manifest.
- `FontDownloadActivity.h`: extend manifest file metadata with `crc32`
and declare checksum helper.
- `FontDownloadActivity.cpp`: parse `crc32` from manifest, compute CRC32
of downloaded files using `esp_rom_crc32_le`.

Add a complete SD card font subsystem that enables users to install and
use custom fonts beyond the three built-in families. This combines the
back-end firmware support (#1327) with the font configuration, build
pipeline, CI distribution, and user-facing management UI (#1392).
Core font system:
- Custom .cpfont binary format (v4) with multi-style support (regular,
bold, italic, bold-italic) packed into a single file per size
- On-demand glyph loading from SD card with two-pass prewarm rendering
to bulk-read glyphs per page, achieving near-flash performance for
Latin text (~697ms vs ~681ms) and viable CJK rendering (~32% slower)
- Persistent advance cache for layout measurement without SD I/O
- Overflow ring buffer for glyph cache misses during rendering
- Memory-conscious design: only advance tables kept in RAM; glyph
bitmaps, kern tables, and ligatures loaded on demand from SD
Font management:
- On-device WiFi download from GitHub Releases with manifest-based
discovery, install/update detection, and progress UI
- Web interface font upload, listing, and deletion via /fonts page
- Manual SD card copy to /fonts/ or /.fonts/ directories
- Font selection integrated into Settings > Reader > Font Family
Build pipeline:
- Declarative YAML config (sd-fonts.yaml) as single source of truth
for the 17-family font library (serif, sans, mono, accessibility)
- Python converter (fontconvert_sdcard.py) for TTF/OTF to .cpfont with
FreeType rasterization, class-based kerning, and ligature extraction
- Parallel build orchestrator with variable font instance extraction
- CI workflow publishing versioned + stable releases to a dedicated
crosspoint-fonts repository with auto-incrementing revision tags
- Centralized version constants (cpfont_version.py) shared across
build tooling and CI, with firmware headers as manual sync points
Additional fixes:
- CJK characters no longer get hyphens inserted at line breaks
- Advance table eliminates 30+ second stalls during CJK section
indexing for paragraphs with >512 unique codepoints
Closes#930
