Trinket glyphs used from onebit.png (col,row of 16 px cells), tinted in code with six enamel inks:
 Heart 39,10 · Card 32,16 · Crystal 34,10 · Rook 43,20 · Key 32,11 · Gem 33,10 · Ink pot 33,19 · Egg 34,17 ·
 Pear 34,18 · Clover 44,13 · Potion 32,13 · Cactus 6,1 · Crown 43,2 · Ring 45,6 · Trophy 40,16 · Cheese 34,16 ·
 Amulet 45,7 · Note 39,16 · Top hat 45,2 · Scroll 33,15 · Coin 41,3 · Hourglass 39,12 · Money bag 42,4 · Carrot 34,20 ·
 Sunstone (gem) 32,10.
 Round 2 swaps (review 1): Apple 33,18 -> Card 32,16 (Heart and Apple were both small red rounds); Rook 40,20 (an "=" sign)
 -> the real rook cell 43,20; Fish 33,17 -> Ink pot 33,19 (it was confused with the Gem); Die 44,14 (read as a box) -> Cactus 6,1.
 The copper ink was deepened to #8c4a1e so it no longer sits next to amber.

Original, made for Tap Tavern (no CC0 asset covered them): the Glintwings magpie pixel maps and accessories,
Sir Rustle the weathercock, the dithered golden-hour sky, rooftops, clock-tower chimney and twig nest, the tile bodies,
sparkles and feathers (all drawn in code in public/mahjong-art.js and public/mahjong-render.js), and the library
cover and banner (public/assets/covers/mahjong.svg, mahjong-banner.svg), which embed a crop of onebit.png and
Pixelated Elegance.
