about

nx_ad_banner.nx -- LIB: the BANNER GENERATOR for the performance ad engine. Advertisers generate real STATIC or DYNAMIC display banners (IAB-sized, themed) for placement in the one-ad-per-page slot. EXTENDS nx_ad_serve's clean "Brought to you by" model from a text byline to a full creative, while KEEPING every privacy/security invariant BY CONSTRUCTION: * ZERO third-party JS -- no <script>/<iframe>/<object>/<embed>/src= ; DYNAMIC = pure CSS @keyframes animation (no JS), so a banner can NEVER carry a surveillance auction or third-party script. * SELF-CONTAINED -- no external fetch (no src=, no url(http...)) -> no off-site beacon. Visuals are CSS (solid + accent) + text only; no <img src>. No per-user targeting -- "systems not people". * BOUNDARY-ESCAPED -- sponsor/headline/body/cta are external input -> HTML-escaped (rule 12); the click LINK is scheme-validated (https/http/ relative only) so a `javascript:`/`data:` URI XSS is neutralised to '#'. * SCOPED -- a per-banner class suffix scopes the inline <style> so multiple previews on one builder page never collide. DRY: composes nx_ad_serve (as_append / as_append_escaped / as_has_thirdparty_js / as_len / as_contains). IAB sizes + themes are NAMED here (code-default tier of the config hierarchy); migrate to adcfg:bannersizes in the sovereign store (nx_ad_store) as a follow-on. license_tier: ORIGINAL
