Implementation steps (SOP)
Project setup:
Initialize: Git repository with src/ (partials, assets) and dist/ (final).
Configure: Prettier, ESLint, HTMLHint; add commit hooks via Husky for pre-commit linting.
Architect the template:
Partials: header, navbar, post-card, pagination, footer as Jinja2 includes.
Layouts: index, post, page; ensure a single H1 and logical H2/H3 hierarchy.
Design system and dark mode:
CSS variables: color-scheme, spacing, typography tokens.
Dark mode: prefers-color-scheme plus toggle with localStorage.
SEO and structured data:
Meta: dynamic title patterns, meta description fallback from first 160 chars.
JSON-LD: Website, Organization, BreadcrumbList, Article injected per template.
ToC and internal links:
ToC script: parse H2/H3, generate anchors, insert after intro.
Smart linking: related posts by label/category; last-paragraph crosslinks.
Performance hardening:
Images: convert to WebP, responsive sizes, lazy loading; decode async.
JS strategy: defer, async, tree-shake; inline critical CSS, preload fonts.
XML generation and validation:
Build script: Python merges partials → HTML → Blogger XML wrapping.
Validate: xmllint, HTMLHint; reject build on any error.
CI/CD pipeline:
GitHub Actions: lint → build → Lighthouse CI → attach artifacts; fail under thresholds.
Release: tag version with changelog; manual upload or API script.
Accessibility polish:
Contrast: WCAG AA; focus states; skip to content; alt text for all images.
