[PATCH 0/5] fix broken mobile layouts across views

[Rito Rhymes]

This patch series fixes mobile responsiveness bugs that currently break
page layouts in cgit. The approach is adaptive rather than transformative:
it preserves the legacy desktop layout, adds targeted mobile constraints
at <=768px, and prevents content from escaping its containers and
breaking layout.

Rationale

Software development remains largely desktop-first, but contributors
increasingly browse history, read logs, review diffs, and share links
from mobile devices while away from a workstation. This patch series
improves day-to-day usability for contributors accessing cgit on small
screens, while preserving existing desktop behavior.
