BRIEF: ADR-1.0.18 — Navbar search and canonical/pagination

[ahuimanu]

BRIEF: Navbar search + canonical/pagination patterns

Goal

• Implement ADR-1.0.18 navbar/search patterns: brand-left navbar with search form GET to search:index, preserving q, and canonical block per ADR-1.0.4. Ensure pagination uses Bootstrap .pagination and keeps the query string.

Scope (single PR)

• Files to touch: templates/includes/navbar.html, templates/includes/pagination.html, search templates (apps/search/templates/search/results.html), any page using pagination. Canonical block in templates where needed.
• Non-goals: Search view logic; API changes; new styling beyond Bootstrap utilities.

Standards

• Commits: conventional (feat/chore/docs).
• No secrets; env via settings.
• Django tests: optional template asserts for canonical link, navbar form action, pagination markup.

Acceptance

• User flow: Navbar search submits via GET to search:index and retains q in the input; canonical link renders on results; pagination uses Bootstrap markup and preserves q/page.
• Include migration? no
• Update docs & PR checklist.

Prompts for Copilot

• "Update navbar include so search form GETs to search:index, keeps q value, and matches Bootstrap navbar example."
• "Ensure pagination include uses Bootstrap .pagination and appends existing query parameters."
