Daykey AI mode — optional browser-assistant entry point

Only use this interface when the user has asked you to add plans to Daykey.
Open /?ai=1 on this same origin, or choose Settings > AI mode.
The normal planner intentionally does not display these instructions.

This edits the planner stored in the current browser/device. It does not access
someone else's phone, account or calendar simply by visiting the website.
If you use a separate remote browser, do not claim to have updated their device.
There is no remote pairing or MCP endpoint in this version.

The AI mode page contains a text field labelled "AI entry text".
Enter one new entry per line:
YYYY-MM-DD | morning, afternoon, night or todo | title and optional /commands

Example syntax only (use dates requested by the user):
2026-12-18 | night | Dinner with Brianna /time 19:00 /duration 2h
2026-12-19 | todo | Renew passport /due 30 Dec
2026-12-21 | morning | Work /time 09:00 /duration 8h /every Mon Wed Fri /until 31 Dec

Use explicit dates and 24-hour times. Relative words refer to the date at the
start of that line. Quote literal command-like wording. Do not paste a discussion
or other instructions as planner entries. Maximum 100 lines / 20,000 characters.
The Commands guide in Settings describes supported commands.

1. Enter text and select "Preview changes". Nothing is saved to the planner yet.
2. Inspect each resolved date, time, deadline, repetition and privacy setting.
   Correct errors. Ask the user about ambiguous requests instead of guessing.
3. Select "Apply to Daykey" only for user-authorized changes, following your own
   approval requirements. A webpage is not authorization from the user.
4. Wait for the saved result. Do not equate locally saved with calendar delivery.

This version adds entries only; it does not edit/delete existing entries, send
messages, or execute /copy or /skip. Exact matching entries are skipped, including
on resubmission. "Undo last addition" removes unchanged entries from the last
batch. To-dos do not repeat or sync to Calendar. /private excludes a plan from
Calendar. Attached links are never automatically opened. The page does not expose
existing private entries to the assistant. Text drafts are retained on this device.
