Wire the seam end to end: the background mirrors config.local.json into
storage (a content script would need web_accessible_resources, which would
expose the email to the mairie page), and the content script lays the computed
values into the form.
The layer is deliberately thin and untested: all the logic lives in
formulaire-valeurs.js. It never writes an empty value, never touches the image,
the honeypots or the CSRF tokens, and never submits: a human reads and sends.
A banner states what is left to do, and warns when a field could not be filled,
so that a silent failure stays diagnosable.

Manifest V3 (Firefox keys: background.scripts, host_permissions), a
background event page that opens a standalone list page on toolbar
click, and the placeholder list page (HTML/CSS/JS vanilla). No build
step. extension.test.ts validates manifest shape and referenced files.
