Introduce methods to temporarily release the 48KB framebuffer during memory-intensive chapter builds, allowing the memory to be reused. Add font metadata query methods (hasGlyphMeta, ensureAdvance) that check glyph existence and fetch advance metrics without loading full bitmap data, avoiding expensive SD reads during layout measurement.
Host-side gtest unit tests for crosspoint-reader. Build and run: cmake -S test -B build/test cmake --build build/test ctest --test-dir build/test --output-on-failure -j Run a single suite directly: cmake --build build/test --target StreamingJsonParserTest build/test/streaming_json_parser/StreamingJsonParserTest --gtest_filter='*' Google Test is fetched via CMake FetchContent on first configure; the pinned version lives in test/CMakeLists.txt.
