Detailed Description

Rasterizes a baked SVG into a fixed RGB565 framebuffer and hashes the result (#143) – the vector counterpart to the raster stb_image gates ereader_image (PNG) and ereader_jpeg (JPEG). It reads the document's intrinsic size from its viewBox, maps that box onto the framebuffer, and fills the supported shapes (<rect>, <circle>, <polygon>) through the reflow SVG renderer (#112, #141). The rasterizer allocates nothing; its only side effect is drawing through ra8_gfx. Headless – no panel, SDRAM, touch or SD.

The SVG path is a separate rasterizer from stb_image, so the raster gates say nothing about it. Here any drift in the SVG parse, the shape rasterizer or the viewBox-to-box transform changes the hash. The renderer is host-tested in apps/shared_libs/reflow/tests/src/test_svg.c; this app is what runs it on the target and pins the rendered output.
