Restored the full detailed roadmap content in BIG_PICTURE_ROADMAP.md from the last detailed revision (before it was flattened).

Going forward, I’ll treat this file as status-only and only change [ ], [.], [x].

-# BIG_PICTURE_ROADMAP
-
-## Roadmap Patch Guidance For Next PR
-This bundle intentionally provides a text-only roadmap direction for the next Codex step because the prior session reported broken icon rendering in the big picture roadmap.
-
-### Required Cleanup
-- remove broken decorative icons from the affected network/debug roadmap area
-- use plain text headings only for the relevant tracks
-- preserve existing ordering and surrounding roadmap structure
-
-### Required Network/Debug Sequence
-- Track N - Network Sample Foundation
-- Track O - Host / Client Sample
-- Track P - Divergence / Trace Sample
-- Track T - Server Dashboard
-- Track U - Server Containerization
-
-### Level Mapping
-- Level 11 - Network Games
-- Phase 13 - Network Concepts, Latency & Simulation (1301-1315)
-
-### Plain-Text Upcoming Tracks
-Track T - Server Dashboard
-Track U - Server Containerization
-
-### Notes For Codex
-- apply this as a minimal cleanup/update to the existing file
-- do not introduce new icon glyphs or emoji in the repaired section
-- keep wording aligned with `docs/dev/NETWORK_SAMPLES_PLAN.md`
