refactor(modals): consolidate modal.js + modal-router.js as inline/routed
Two modal pipelines coexisted after the URL-addressable pilot — modal.js
(inline, ~30 lines) and modal-router.js (routed, ~150 lines) — operating
on different attribute namespaces and exposing different APIs. Future
modal authors had two systems to learn with no naming convention to
help them pick the right one for a given use case.

Consolidates both into static/js/modals.js with two clearly-named
pipelines and a single window.modals.* API:

  Inline modal — content pre-rendered in the page.
    Hooks:  data-inline-modal-open="<dialog-id>"
            data-inline-modal-close
    API:    window.modals.openInline(idOrEl)
            window.modals.closeInline(idOrEl)
    Use:    confirmations, transient prompts, in-page forms without
            URL value.

  Routed modal — content fetched from a URL, ?modal=<path> in URL,
            with history + share-link + refresh-survival.
    Hooks:  <a data-routed-modal href="<path>">
            data-routed-modal-dismiss
    API:    window.modals.openRouted(path)
            window.modals.closeRouted()
    Use:    content with standalone-page meaning.

Single document-level click delegation handles all four attribute
hooks; one DOMContentLoaded handler binds dialog 'close' / 'cancel' /
backdrop on the routed slot; shared popstate and htmx:responseError
listeners. Behaviour unchanged — pure rename + colocation.

Renamed across 11 templates and files-overlay.js. Old data-modal-*
attributes and window.openModal/closeModal globals are gone — clean
break (no back-compat shims). AGENTS.md "Modals: inline vs routed"
section documents the decision guide for new modals.

Verified: 573 backend tests pass. 5/5 Chromium smoke checks pass
(inline open/close, Esc, backdrop, routed open+save, routed Esc).
Console clean.

l4d2-web-app

Flask web app for managing L4D2 servers through user-private blueprints.

Key v1 behaviors

  • Local username/password login; no public signup
  • Admin-managed overlay catalog
  • Private blueprints per user
  • Server creation from blueprints (live-linked; no per-server blueprint overrides)
  • Async job model with persisted command logs in job_logs
  • Desired vs actual state model
  • Live logs for jobs and servers via SSE endpoints
  • Host operations go through l4d2ctl via a local host command runner, not direct l4d2host imports

Frontend constraints

  • Server-rendered templates (Jinja)
  • Vendored HTMX (static/vendor/htmx.min.js)
  • Custom CSS only
  • Tokenized, consistent link and accent colors

Development

From the workspace root (../):

uv sync          # creates .venv, installs l4d2host + l4d2web editable, plus dev deps
uv run pytest l4d2web/tests -q

Configuration

The web app reads these settings from the environment:

  • DATABASE_URL: SQLAlchemy database URL, for example sqlite:////var/lib/left4me/left4me.db.
  • SECRET_KEY: Flask secret key used for sessions and CSRF-sensitive state.
  • JOB_WORKER_THREADS: number of background job worker threads.

In the systemd deployment, environment is loaded from /etc/left4me/host.env and /etc/left4me/web.env.

Admin Bootstrap

Create the first admin account with the Flask CLI. Provide the password through LEFT4ME_ADMIN_PASSWORD:

LEFT4ME_ADMIN_PASSWORD='change-me' flask create-user <username> --admin
