Plant assistant mockup: operator, management, sales

docs/plant-assistant.html (test site /demos/plant-assistant/): the
plant assistant on vinyl-ai as three roles see it. Operator at the C1
press kiosk in Thai or English with push to talk (non-fill rejects
explained from cycle rows, lot change and press hall humidity, the
stamper change procedure quoted from the approved version, a lot on
hold, a refused price question, a safety question answered word for
word); management at a desk (output and yield per press against the
plan basis, steam per record against scale.md, orders at risk, the
weekly note, payroll refused); sales on a phone (order status and ship
window, repress feasibility from archived mothers and the standby
calendar, repress leads, a test pressing status, fans' addresses
refused). Each answer carries numbered sources; the side panel shows
the tool calls (ERPNext as the asker's role, the PostgreSQL replica,
VictoriaMetrics, documents, event log) on premises with the internet
not used; action buttons create drafts only. Deep links
#role=<role>&q=<id>, light and dark theme. Invented data; names match
the factory console demo.
