<!--
AGENT NOTES — contract for AI/coding agents editing this file:
- The spreadsheet document lives ONLY in the JSON block directly below this
comment: the script element with id "sheet-data" (type application/json).
Everything else in this file is application code/UI.
- Document format (v2):
{ "title": string, "theme": "auto" or a theme id from THEME_LIST in the
app code (43 built-in themes),
"lang": "auto"|"en"|"ja" (UI language; "auto" follows the browser),
"activeSheet": number, "sheets": [ { "name": string, "data": [[...]] } ] }
Each sheet's data is a JSON 2D array of strings; data[0] is that sheet's
header row. All rows in a sheet have equal length (the app pads ragged rows
on load). Cells are plain strings; numbers are coerced to strings.
A legacy bare 2D array is still accepted on load and migrates to v2 on the
next save.
- Keep the formatting produced by JSON.stringify(doc, null, 2): 2-space
indent, LF line endings. This keeps saves diff-stable.
- Do NOT rename, duplicate, or reformat the opening tag of the sheet-data
block. The app locates the block with a regex keyed on id="sheet-data";
extra attributes are tolerated but the id must stay.
- If a cell value contains "<", write it as \u003c in the JSON so the block
cannot terminate early. Cell newlines are stored as \n. The in-app save
applies this escaping automatically.
- Co-editing semantics: the browser app keeps the document in memory. Saving
from the browser re-reads this file from disk and rewrites ONLY the
sheet-data block, so code edits elsewhere in the file survive a user save.
If you change the JSON while the file is open in a browser, the user should
press 再読み込み before saving; the app also warns when the on-disk block
changed after load.
- App code lives in the script element with id "app-code" at the end of body.
Entry points: render(), reloadFromFile(), saveToSameFile(), exportHtml(),
exportCsv(), initialize(). UI strings live in the MESSAGES catalog (en/ja);
keep identifiers English.
