add a stylesheet link and the standard responsive viewport meta tag
to every page template. purely additive - no markup or selector
changes - so existing cypress assertions and page js id hooks remain
intact. with this commit every page picks up the base styling from
app.css.
introduce a single shared stylesheet under public/css. this first
section covers a minimal reset, warm/readable design tokens (color,
typography, spacing, radii, shadows), and base element styling for
headings, links, lists, forms, and buttons. layout primitives and
component classes follow in subsequent commits.
Forcing every call site to be explicit eliminates a class of bugs where an unintended default silently slips through. Codifies the convention already established by prior commits (cd40483, b41652a, 8eb0f23).
Forcing every call site to be explicit about admin status and
password eliminates a class of bugs where an unintended
isAdmin=false or empty passwordHash could silently slip through.
The CreateUserTest case that asserted the isAdmin default is
dropped since the default no longer exists.
Replace the strict "one commit per file" guidance with grouping by
related changes, while keeping the small-and-focused intent. Add
explicit guidance on when to include a commit body and how to format
it (blank line separator, ~72 col wrap).
Applied to both backend and frontend prompt templates.
