The --color-surface-alt token was never defined in :root or :root[data-theme="dark"],
so the var() fallback hex literal always won — leaving 12 surface sites with
zero dark-mode treatment. Same pattern as t-paliad-087 / t-paliad-150 / t-paliad-291.
Issue #138 surfaced four panels visibly broken in dark mode:
1. submission-draft no-project banner ("Kein Projekt zugeordnet…") — white-on-white
2. submission-draft preview header ("Vorschau / Read-only Vorschau…") — white-on-white
3. smart-timeline rule-chip (e.g. de.null.bpatg.berufung in Vorhersage rows) — grey-on-grey
4. submission-draft addparty manual form (Manuell / Aus DB / Name / …) — white-on-white
Eight more latent sites with the same root cause are fixed in the same pass:
.submissions-new-chip:hover, .submissions-new-project-item:hover,
.submission-draft-import-row, .submission-draft-addparty-search-projref,
.collab-invite-hint, .smart-timeline-status-icon,
.smart-timeline-kind-chip--projected, .smart-timeline-add-choice:hover.
Each site repointed to the semantically correct existing token
(--color-surface-2 for #fafafa, --color-surface-muted for #f4f4f4,
--color-bg-subtle for #f7f7f0, --color-bg-lime-tint for the lime-tinted
collab-invite-hint). All four target tokens are defined in both :root
and :root[data-theme="dark"]. No new tokens introduced.
Light-mode hex values are functionally identical (#fafafa==#fafafa,
#f4f4f4≈#f3f4f6, #f7f7f0≈#f7f3f0).
Verified: bun run build clean; Playwright screenshots of the four panels
in both light + dark modes show correct rendering.
