/* ============================================================
   SHARED — task-guide layout for /guides/<slug>
   Link this from any plain task guide:
       <link rel="stylesheet" href="{% static 'css/guides/task-guide.css' %}">

   Used by:
     guides/set-up-customer-tipping.html
     guides/brand-your-invoices.html

   Rendered as a fragment inside tools/guides.html on the v1
   base.html Bootstrap shell. That shell supplies no <h1>, no TOC
   and no section chrome (it emits only rendered_content), so the
   fragment brings its own markup and this file dresses it.

   Everything is scoped under .tg and self-sufficient — it must
   not assume any V2 token file is loaded on this route.

   Lighter than css/guides/jobs-vs-invoices.css on purpose: that
   page is a full docs layout with a sidebar and a decision
   engine, and keeps its own stylesheet. This is the plain
   several-sections-and-steps guide most topics need, so it is
   shared rather than copied per slug.

   Anything genuinely one-off for a single guide belongs in that
   guide's own sheet, not here.

   MOBILE-FIRST: base styles = phone; desktop layered on.
