/**
 * Deployment-wide settings: one row, named columns.
 *
 * Phase 4.6c needs somewhere to keep what the CMS calls itself and what colour it is. A key/value
 * table is the reflex, and it is the wrong shape here — every read comes back as text needing a
 * parse, nothing can say which keys exist, and a foreign key on the logo is impossible. Named
 * columns get all three from the schema, and adding a setting later is an `ADD COLUMN` rather than
 * an untyped string appearing in a blob.
 *
 * One row is not a limitation being worked around: SCOPE settled "one site per deployment", so a
 * second row would describe a site that cannot exist. The check constraint says so in the schema
 * rather than in a comment, and the writer upserts on the primary key.
