/*
Module intro tour - animated mockups + dialog chrome.
See apps/web/module_intro_content.py's module docstring for why this
is a SEPARATE file from style.css: a genuinely standalone new visual
subsystem (not a tweak to something already in style.css), loaded
globally via base.html same as tailwind_built.css/style.css.

Six reusable animated "kind"s, mixed and matched across every module's
steps (module_intro_content.py) instead of one bespoke animation per
step - same "few reusable building blocks" principle the rest of this
app's UI already follows:
  - search    - typing ticker + a score meter filling in
  - list-add  - a new row sliding into a list, checkmark pulse
  - sync      - a spinning refresh icon + a "Synced" label
  - signal    - a dot travelling across a bear->neutral->bull gauge
  - progress  - a row of checklist nodes filling in in sequence
  - game      - bouncing candle-style bars + a floating score pop

All ambient step animation is pure CSS (`animation-iteration-count:
infinite`) - no scroll-triggering or per-frame JS needed, so a step
looks equally alive whether the visitor lingers 2 seconds or 20.
module_intro.js only handles dialog open/close, step navigation
(toggling the `hidden` attribute), and the mark-seen network call.
