Me Here 111da49b5a PM_K-1 CircuitPython: fix MemoryError + red/blue swap (from on-board test)
On hardware the app rendered, beeped and took input, then died with MemoryError at
the text Bitmap alloc — the two ~37KB base64 font strings stayed pinned in RAM. Move
the fonts to small binary files read at boot (font_m.bin / font_l.bin), drop the
base64 + binascii, and gc.collect() before each text bitmap. code.py 56KB -> 20KB and
RAM use drops ~37KB+. Also: cyan rendered as yellow (R/B swapped) -> MADCTL 0x40 -> 0x48.
Bundle + README updated to include the font blobs. (LED still needs the neopixel lib.)

# Assemble the deployed single-file pages from source + shared partials + assets/.
#
# Every page (the Concepts landing, the editor app, and the device/form-factor
# pages) is a source that shares code via markers:
# /*@BUILD:include:src/<file>@*/ inlines a shared partial (engine, seed lists, base CSS, header/footer/chrome)
# @BUILD:favicon@ / @BUILD:logo-*@ inline base64 assets (voices are all synthesized — no samples)
# This resolves them so each built page in dist/ is one self-contained file
# (zero deps, works fully offline). deploy.sh runs this first. dist/ is generated —
# don't edit or commit it.
