Rolling back is now non-destructive: instead of truncating the future,
it restores the target checkpoint's snapshot and points
Game.rollback_head_checkpoint_id at it. Later checkpoints/events are
kept and rendered greyed; rolling forward to one redoes the rollback
(same endpoint). The abandoned future is discarded only when a new
action is taken from a rolled-back state -- maintain_rollback_history
truncates it, clears the head, and bumps rollback_timeline_version,
now the sole trigger for the frontend log reset.
- Game.rollback_head_checkpoint_id (nullable; in SNAPSHOT_EXCLUDE) +
Alembic migration.
- crud_rollback: rollback_to_checkpoint sets the head (None at latest);
_discard_future + head-clear + version-bump moved into the next scene
action's capture.
- EventLog.svelte: greyed future, redo (forward) affordance, a "rolled
back" banner; dropped the now-misleading destructive confirm.
- Tests rewritten for head-pointer semantics (+ redo, action-after-
rollback truncation, scene-end head clear); HTTP integration test
extended to drive the full cycle over the wire.
Verified end-to-end in a browser: rollback greys the future and reverts
live state (captaincy/ranks), redo restores it, no errors.

Full-state JSON snapshots let a scene be rolled back to an earlier
action. All game state lives in game_id-scoped tables, so a checkpoint
is just a serialized dump of the gameplay rows and rollback restores
it -- sidestepping deterministic replay (the deck shuffle is
materialized into state and captured verbatim).
- Checkpoint table + GameEvent.checkpoint_id (tri-state) +
Game.rollback_timeline_version (models.py, Alembic migration).
- crud_rollback.py: serialize/apply/capture/seal-purge/rollback.
- Capture is driven by the broadcast middleware: snapshot per action
while in the `scene` phase, seal+purge otherwise. Confined to the
current scene; older scenes' checkpoints are purged at scene end.
- POST /game/{gid}/player/{pid}/rollback (routes_rollback.py),
server-enforced for Admins and Deep players.
- EventLog.svelte: per-event rollback buttons + timeline reconciliation.
- Remove the orphaned /scene/rollback per-card-play undo (dead code
since d7f8483, never wired up; superseded by full-state rollback).
Phase 1 truncates the future immediately; the greyed/undoable redo is
deferred to Phase 2.

CSS refactor: every color, font, radius, and shadow is now defined once
in theme.css; all other styles derive translucent variants with
color-mix(), so re-theming means editing one file. Removed the
duplicate core.css/style.css import chains, dead styles, and the
Bootstrap/Tailwind orphan classes that were silently unstyled
(the main reason the splash page looked broken).
New "Lantern & Brine" look: brass and parchment on a lantern-lit
ink-navy night, Pirata One wordmark with Alegreya SC/Sans body fonts
(self-hosted via fontsource — they were previously referenced but
never loaded), parchment-faced playing cards, and a rebuilt splash
page. Inline color styles in components were replaced with semantic
classes (prompt-box, notice-banner, status chips, etc.), the rulebook's
embedded palette was updated to match, and the leftover Vite favicon
and "frontend" page title were replaced.
