3-column grid layout for field rows (label / input / hint).
Compliance prompts + Blockers blocks have their own backgrounds.
Soft blockers amber + left border, hard blockers red + left border —
matches the spec's protocol.
Token pattern + dark-mode @if branch (CLAUDE.md rule: Odoo 19 doesn't
flip dark mode via runtime DOM class; we branch at SCSS compile time
on $o-webclient-color-scheme).
