Two build-time steps shrink the embedded Web UI (html/) from 113,015 to 34,784 bytes (30.8 %): - tools/minify.py (new): string-literal-safe minifier that strips comments and indentation; comments are pure overhead on the wire, so the transfer size drops already before gzip (113,015 -> 101,498). Binary files (.ico) are copied through unchanged. The output goes to output/html_min/, the new fileadder input. - fileadder -z: gzip-compresses every added file (zlib gzip format, Z_BEST_COMPRESSION); the generated f_data entries carry a gzip flag. tools/Makefile links the tool against -lz. - httpd: adds "Content-Encoding: gzip" for flagged entries; the 8051 only copies compressed bytes, decompression happens in the browser. The JSON API stays uncompressed. Fixes required to make the sizes deterministic: - fileadder terminated files at data_read + 1, so the strlen()-based size computation depended on uninitialised buffer content; the NUL now lands directly after the content. - version.h was .PHONY, so every build rewrote it while parallel builds could read a half-written copy. - the file list was unscoped and missed .css/.ico; it is now scoped to html/ and covers all embedded types. Measured with make MACHINE=KP_9000_6XHML_X2: data block end moves from 0x5b977 to 0x487e0 (~78 KB freed on a 512 KB image). Verified with MACHINE=PCB_K0402WS_V3 and on real hardware (PCB-K0402WS-V3).
