-**DI-container adoption.** Microsoft.Extensions.Hosting plus `ILogger<T>` modelled on Lightless's `PluginHostFactory`

-shims (`IPluginLogProxy`, `IPlatformUtil`) were paving the way for. After that, the Wine/Linux scroll-rubber-band spike
-deferred from v1.4.10 (Reserve-A cancelled — Windows users never saw it) plus the First-Run-Wizard rework that lets users
-opt into the curated defaults instead of just picking a privacy profile.
+**Honorific Full Gradient Port plus FontAtlas-Defer for a 10× HITCH cut.** v1.5.0 closed the DI-container cycle with
+no performance penalty against Chat 2 (77 ms vs 74 ms median first-frame HITCH), but the cross-plugin baseline against
+Lightless Sync and XIVInstantMessenger surfaced a clean optimisation: both plugins defer their font-atlas build until
+after `Finished loading` and sit at 6-7 ms HITCH, an order of magnitude below the ~75 ms floor that Chat 2 and HellionChat
+share. v1.5.1 ports that pattern. Plus the Honorific gradient render path — DTO is gradient-ready since v1.4.7, only the
+Wave / Pulse animation port remains. After that, First-Run-Wizard rework with curated defaults beyond the three privacy
+profiles, then FR localisation (Hezcal native-speaker review confirmed), then the Plugin Integrations Wave 2-6
+(Context-Menu, NotificationMaster, Moodles, ExtraChat, XIVIM Quick-DM). Wine/Linux scroll-rubber-band spike sits as a
+low-priority Linux-only investigation at the tail.

+## v1.5.0 — DI Foundation and Service Refactor (released 2026-05-17)
+
+Major architecture cycle. Plugin bootstrap moves to a generic-host DI container
+(`Microsoft.Extensions.Hosting` + `IServiceCollection`) modelled on Lightless Sync's `PluginHostFactory`. Service
+logging migrates from the static `Plugin.LogProxy` locator (the F12.2 shim from v1.4.7) to typed
+`Microsoft.Extensions.Logging.ILogger<T>` via constructor injection, bridged over Dalamud's `IPluginLog` by a custom
+`DalamudLogger` trio. 18 instance-class services move to ctor-injected loggers across four slices: data layer,
+IPC/integrations, UI window layer, and root. `Plugin.LogProxy` stays for the eight buckets ctor injection cannot
+reach — static helpers (`EmoteCache`, `AutoTranslate`, `MemoryUtil`, `WrapperUtil`), Dalamud-reflected types
+(`Configuration`), the `Message` data class, and instance classes that only log from static methods (`FontManager`,
+one `GameFunctions` site). Plugin.cs finishes at 1012 lines, virtually identical to the pre-cycle 1013 (-1 netto): the
+new Phase-1 host build and `Plugin.X` bridge wiring trade out exactly the service and window allocations that previously
+lived in `LoadAsync`. Cross-plugin baseline (10 reload-stress runs, 51 active plugins): HellionChat first-frame HITCH
+77 ms median, Chat 2 v1.40.2 74 ms median — no DI penalty. The deferred-font-atlas pattern from Lightless and
+XIVInstantMessenger is the v1.5.1 follow-up. User-visible: slash-command insert fix cherry-picked from ChatTwo upstream
+`ee7768ac` — pasting a slash command into the chat input now replaces existing input instead of concatenating.
+Migration v17 stays.
