Minimal built-in cookie notice with configurable style and storage (MVP)

[aplgr]

Hi,

I would like to propose a small built-in cookie notice for Blowfish.

The goal is an MVP:

• simple notice banner
• one button
• state stored in browser storage
• configurable via params.toml

This would not be a full consent manager or compliance solution. It would just provide a minimal built-in base that could later be extended into a more complete consent flow if there is interest.

Proposed config:

[params.cookieNotice]
  enabled = true
  style = "simple"
  storage = "localStorage"   # localStorage or sessionStorage
  storageKey = "blowfish_cookie_notice_ack_v1"
  privacyPolicyPageRef = "/privacy-policy"
  image = "img/cookie-notice/cookie.svg"
  imageAlt = ""

For internal links, I think privacyPolicyPageRef would be better than a fixed URL. That would match the way Hugo resolves internal page references and would make the privacy policy link work correctly in multilingual sites as well.

Why I think it could fit Blowfish:

• common requirement for many sites
• fully optional and disabled by default
• small implementation footprint
• style-based structure leaves room for future variants

Initial scope would stay minimal:

• one simple banner style
• external JS/CSS assets
• optional small image
• i18n-ready strings
• multilingual privacy link via page reference
• no categories
• no accept/reject logic
• no script blocking

If this direction makes sense, I can prepare a PR against dev.
