# Le Cadran — public exhibits

Sub-dossier of `FI-PROJ-006` (ATLAS). Public route: `/projects/atlas/le-cadran/`.

These files are rendered by ATLAS, not written here. They are copied from the
public ATLAS repository and published unchanged, so the dial on this site is
the dial the train actually draws. `sheet.html` and `dial.svg` are from commit
`b5cf574` (PR #62, https://github.com/SCADUMEN/ATLAS/pull/62). `live.html` is
from commit `d5cb840` (PR #63, https://github.com/SCADUMEN/ATLAS/pull/63), which
escapes typed text in the live readout.

Two changes, both mechanical:

- `live.py` writes a page fragment (no doctype) for the Artifact viewer. To
  serve it standalone, `live.html` prepends a document head (doctype, `lang`,
  charset, viewport) and is otherwise the source byte for byte.
- `dial.svg` is the first `<svg>` element of the sheet (Plate 1, the trace for
  "run Publish, security check"), saved on its own with an XML declaration.

To refresh: re-render in ATLAS (`python3 rouage/dial.py`, `python3 rouage/live.py`),
repeat the copy, and update the commit and checksums above. Prettier ignores
the exhibits (`.prettierignore`) so formatting never rewrites them.
