Summary: Drafted multilingual tool_*_description updates so each tool SEO description includes process steps and a concrete example.
[question] 用户要求：默认规则修改：工具页面 SEO 要求，描述里面需要包含工具计算过程和逻辑案例。
[try to solve]
Produced a full suggested update list for common tool_*_description keys across src/site/i18n/*.ts (en, zh, es, fr, de, ru, pt, ja, id, ar). Every draft includes calculation/processing steps plus a concrete example.
English examples (pattern used for all locales):
tool_headers_description: Fetch headers server-side (HEAD, fall back to GET); follow redirects; block private hosts; example covers CORS / Cache-Control / HSTS debugging.tool_markdown_description: Convert Markdown to sanitized HTML with preview (CommonMark parse + sanitize + render).tool_markdown_export_description: Export a full HTML document from Markdown (template, meta, assets, download).tool_bmi_description: BMI = weight(kg) / (height(m))^2 with metric/imperial conversion and category mapping (e.g. 70kg & 175cm → 22.9 Normal).tool_ip_address_description: Public IP plus basic metadata; IPv4/IPv6; optional geo/ISP.tool_squarefeet_description: Area from length × width with unit conversion to sq ft (e.g. 3m × 4m ≈ 129.17 sq ft).
Parallel drafts for the other nine locales follow the same process+example structure with local phrasing. Locale owners should review naturalness before apply; strings can be substituted into matching src/site/i18n/*.ts entries on request (later applied via scripts/apply-i18n-updates.mjs).
