Magnific's SVG export is flat-shaded vector (~550 solid-fill paths, 6
gradients), which converts to pixel art cleanly. tools/svg2portrait.py
rasterises at 16x the target via qlmanage, then takes the most common
colour per 16x16 block — a true pixelate with no blending — and maps to
the 11-colour portrait palette.
Measured on Aki: 19 colours after pixelate, 10 after palette, visually
near-identical. So the portrait palette is sufficient for this art.
Contrast with the bitmap route this replaces: a 48x48 PNG resized in
Photoshop had 1330 unique colours in 2304 pixels, because bicubic
resampling turns flat regions into gradients. Quantising that speckled
badly across the blazer and background.
Also adds tools/pixtool.py — dependency-free PNG decode/encode (no Pillow
on this machine) plus the palette table shared with kissaten.c.

Resolves decision 8: art is generated in PixelLab from written prompts.
docs/ART.md carries the palette spec, the sky/wood slot rule, per-asset
sizes and return format, and prompts for Aki (needed for M3), the rest of
the cast, and the shop background.
art/palette.png (16x1, one pixel per entry) and art/palette_ref.png
(512x64 swatch strip) are generated from g_Palette so the generator and
the build cannot drift apart.
Flags a constraint the palette had hidden: only one literal skin entry, so
portraits use 6 -> 14 -> 4 as a hue-compatible skin ramp.
