1 # Pixel art (#10570)
2
3 The forge's own art, drawn in `src/web/pixel.ts`, no outside assets, no credits, no dependencies. Every pixel is painted
4 with a `fill` attribute from `--fg`, `--muted-fg` or `--card`, so it follows all six themes. Drawings are symbols in the one hashed icon sprite; a page carries a
5 short `<svg>` and a `<use>`.
6
7 - `.px` is a drawing of pixels: crisp, never smoothed. `data-state` says what is true: `working` (a run is going; two
8 frames swap on `--beat`), `landed` (one hop, once) or nothing known (it just stands).
9 - `.px-a` and `.px-b` are the two frames of a working figure. Under reduced motion only `.px-a` shows.
10 - `.px-scene` is the one small drawn scene, on the first-run "No apps yet" (`empty({ scene })`).
11 - `.avatar-px` is an avatar that is a crew member's face instead of initials.
12
13 Motion is one vocabulary, tokens in `style/base.ts`: `--dur-1` (100ms), `--dur-2` (140ms), `--dur-3` (200ms), `--beat`
14 (450ms). A figure never moves without a fact behind it, and nothing moves inside a large inline SVG (the map's faces are
15 still).

1 # Pixel art: the crew's faces (#10570)
2
3 Scout, Mason, Torque, juniper and sentinel have a 16×16 face, drawn in `src/web/pixel.ts` as a grid of characters. No
4 outside asset, no dependency. Each pixel is a rectangle with a `fill` attribute from `--fg`, `--muted-fg` or `--card`
5 (or a mix of the two last), so the art follows all six themes, adds no accent, and passes the page's CSP (a `style=`
6 attribute would be blocked; `test/pixel.test.ts` fails if one is emitted).
7
8 ## Where they show
9
10 - As the avatar wherever a crew member's name appears (`avatar()`), hidden from a screen reader since the name is text.
11 - Working (two frames swapped on `--beat`) beside a run that is running, and in the home's "Being built" rows; still
12 otherwise. Under reduced motion only the first frame shows. A face never moves without a run behind it.
13 - One hop on a run page when the run landed.
14 - Still, on the map's cards.
15 - One small drawn scene, on the "No apps yet" first-run state, and nowhere else.
16
17 ## Both doors
18
19 The terminal has no counterpart on purpose: this change draws the web's avatars and one first-run picture, and every
20 fact they sit beside (who, working, landed) is already text in the TUI. There is nothing to render there.
21
22 ## Motion
23
24 Timings are tokens in `style/base.ts`: `--dur-1` (100ms), `--dur-2` (140ms), `--dur-3` (200ms), `--beat` (450ms).
