  Version History:
    0.1.2 - 2026-04-27 - Burgundy color migration. Per the kickoff
                         §5.8 locked decision (which the Session 3
                         CSS port missed), the destructive color is
                         burgundy not coral. Every hardcoded
                         rgba(255, 100, 80, ...) reference was
                         removed and replaced with a token from the
                         new red companion set in tokens.css 0.1.2:
                         --red, --red-hover, --red-text, --red-dim,
                         --red-bord. Affected: .badge--red,
                         .iq-error-block, .iq-toast--error,
                         .iq-inline-confirm--danger, .iq-danger-zone,
                         .iq-danger-zone-header, .btn-danger:hover.
                         Also corrected several `color: var(--red)`
                         uses to `var(--red-text)` -- burgundy at
                         #7a1f24 is unreadable as foreground text on
                         dark surfaces.
    0.1.1 - 2026-04-27 - Session 3 cont'd. Readability and
                         touch-target floor pass:
                         - .badge font-size 11px -> 12px
                         - .iq-table th font-size 11px -> 12px
                         - .iq-danger-zone-description 13px -> 14px
                         - .iq-tooltip-bubble 13px -> 14px
                         - .iq-modal-close grew from ~34px hit area
                           to 40px desktop / 44px touch
                         Touch-coarse override bumps badge,
                         table-th, and other display small caps
                         from 12px -> 13px on phones and tablets
                         where letter-spacing alone is not enough
                         for field readability.
    0.1.0 - 2026-04-27 - Session 3 initial. Modal extracted from JQiq
                         1.9.5 (the most recent and cleanest modal
                         block in the source apps). Toast pattern
                         from JQiq with the click-to-dismiss error
                         variant from DZIQ 3.22.8. Tables, badges,
                         buttons reconciled across all three apps
                         (the patterns were nearly identical;
                         standardized on the JQiq form). Inline
                         confirm and danger zone are NEW (no source
                         in the legacy apps -- designed to match
                         the RIQ permit-detail inline-delete pattern
                         in the screenshot reviewed during Session 2).
                         Tooltip styles ported verbatim from JQiq
                         lines 1405-1444.
