   NAMING MAPPING (V0 → SBOS):
   ─────────────────────────────────────────────────────────────────────────────
   .sbos-label                       → .ui-2026-label
   .sbos-label-aligned               → .ui-2026-label--inline
   .sbos-field                       → .ui-2026-field
   .sbos-field-row                   → .ui-2026-field--row
   .sbos-field-input                 → .ui-2026-input, .ui-2026-select, .ui-2026-textarea
   .sbos-field-input-readonly        → .ui-2026-input[readonly]
   .sbos-field-error                 → .ui-2026-error
   [data-attention="error"]          → .ui-2026-input--error (via .is-error)
   [data-attention="warning"]        → .ui-2026-input--warning
   [data-valid="true"]               → (native :valid pseudo-class)
   [data-valid="false"]              → (native :invalid pseudo-class)

   EXCEPTION PATTERN MAPPING:
   V0 uses data attributes           → SBOS uses BEM modifiers or state classes
   [data-attention="error"]          → .is-error on field container
   [data-state="disabled"]           → [disabled] attribute

   Design notes:
   - Labels are uppercase with letter-spacing
   - Inputs use --border, --background, --foreground tokens
   - Focus state uses --ring token for outline
