facelift: the scroll story - bento capabilities, dossier cards, series badges, GitOps receipt

02 Capabilities becomes a 4-col bento (Edge AI 2x2 flagship w/ magenta corner radial, Platform
wide, magenta-flavoured security tile, Observability row-completer) driven by span/flavor fields
in skills.ts. 03 Selected Work becomes dossier cards: house-style SVG thumbnails (per-project
motif via DossierThumb), DOSSIER/00N corner tags, 'the argument' line from the outcome field,
chip tags, mono meta footer. 04 Writing cards gain the security-series badge (data/series.ts)
and sit three across. Section numbers glow cyan; a circuit divider (gradient hairlines + two
diamonds) closes the hero. Footer opens with the GitOps receipt - git sha + build date baked at
build time via lib/build-info.ts, zero runtime calls.
