release: v0.4.0 site/README consistency + Web 1.0 re-skin

- Docs site: drop jekyll-theme-cayman for a hand-rolled _layouts/default.html
  (masthead band + middot text nav + footer with last-updated stamp and legal
  line; head re-plumbed with {% seo %}, viewport, favicon); head-custom.html
  fully rewritten to the chosen design tokens - charcoal/off-white/amber,
  Libre Baskerville headings over system sans, square corners, 1px borders,
  flat (no gradients/shadows), mermaid wrapper re-skinned.
- docs/index.md: v0.4.0 status (native widescreen, aim system, rebinding,
  crosshair, rumble, rebuilt overlay); Honest status replaced by the v0.4.0
  release-notes known issues; body anchor-nav line; legal footer moved to
  layout.
- security-and-fidelity-status.md: front matter so {% seo %} titles it.
- README.md: v0.4.0 truth pass (status, Working/Known issues, Deck preset
  2x MSAA / 250% per code, background stats 981 commits / 283 findings,
  comparison table, GEPD-default controls paragraph, earlier builds) plus
  markdown-native motifs matching the site: top anchor-nav line, --- section
  rules, last-updated footer stamp, license badge in the amber accent.
- release-notes: SFTP sideload mention (leftover from the Deck session).

 A native PC port of the original 1997 Nintendo 64 _GoldenEye 007_, compiled
 from the game's [decompiled source](https://github.com/n64decomp/007) with the
 N64's graphics coprocessor (RSP) running in software, the same architecture
 as the [Perfect Dark PC port](https://github.com/fgsfdsfgs/perfect_dark), the
 same Rare "Indy" engine family, one hardware generation apart.
 
-**Status: v0.3.0.** The full single-player campaign runs at a steady 60 fps
-and is completable end to end (all 20 missions playtested); all 20 missions
-load and run clean on Windows, Linux and Steam Deck, and audio (music + SFX)
-plays throughout. The known rough edges — mostly cosmetic rendering defects,
-stretched-not-native widescreen, and missing features — are listed plainly
-under [Honest status](#honest-status).

+**Status: v0.4.0.** The full single-player campaign runs at a rock-stable
+60 fps and is completable end to end (all 20 missions playtested on Windows
+and Steam Deck). This release adds **native widescreen** (on by default —
+undistorted world at your display's aspect, 4:3 menus pillarboxed), a
+**complete aim system** (N64 or centred PC style, for mouse *and*
+controller), **in-game key rebinding** with a GEPD-style default layout,
+**crosshair customization**, real **rumble-pak haptics** on supported
+gamepads, and a **rebuilt options overlay** with fine-tuning rows (frame cap,
+MSAA, draw/LOD distance, HUD scale). The remaining rough edges are few and
+mostly cosmetic — listed plainly under [Honest status](#honest-status).
 
 **This is a pre-1.0 release, not a finished product** — v1.0 is the target
 for a polished, feature-complete build; expect rough edges and missing
 features until then. See the
 [README's Roadmap section](https://github.com/jkdansereau/goldeneye-pc-port#roadmap)
-for direction (PAL/JP support, real widescreen, LAN multiplayer under
-consideration, and more).

 ## Honest status
 
-- **Particle colours** can still drift through a rainbow palette
-  intermittently: one genuine cause is fixed this release, a second hasn't
-  been found yet (D252).
-- **Some muzzle flashes draw an extra erroneous long flash** straight up from
-  the gun, on top of the correct one. Cosmetic only (D303).
-- Water levels show a moving seam between two water patterns (D245);
-  occasional z-fighting on some geometry (D308); in-level security-camera
-  props can occasionally face backwards (D307). Minor and cosmetic.
-- **The front-end Nintendo logo renders as two white blobs** and the Rareware
-  logo's texture filtering looks off (D75).
-- Surface 1's 2D billboard trees render as a solid wall of tree texture
-  instead of discrete sprites; under active investigation (D236).
-- **Widescreen is stretched, not native**: 16:9 stretches the 4:3 frame to
-  fill the display; automatic FOV scaling keeps the framing comfortable and
-  gameplay is unaffected, but a distortion-free native widescreen render is
-  still on the roadmap. Distant geometry can also drop out on the biggest
-  open levels (D249).
-- **Gunshot SFX can sound off during sustained/rapid fire** (D240/D241).
-- **`All unlocked` is highly experimental** — don't enable it until you have
-  at least one save written, or it can break audio and mouse aim
-  (D257/D259/D281).
-- Bond's cutscene positioning is fixed and right the large majority of the
-  time now; on the rare occasion he's off it's a small drift — no more
-  floating or spin-glitching (D173/D292/D243).
-- No macOS/ARM support; no controller rebinding UI yet.
+- On Facility, if gas leaks during Ourumov's monologue he can pause for up to
+  ~10 s before resuming the scripted shootout — a latent race that exists in
+  the N64 original too (where it softlocks permanently); the port detects and
+  auto-recovers it. (D318)
+- With native widescreen on, the F10 options overlay stretches with the
+  window instead of pillarboxing like the front-end menus (legible; cosmetic;
+  the F10 *Native widescreen* toggle restores the old stretched frame
+  throughout). The world/HUD widescreen rendering itself is correct. (D335b)
+- The front-end Rareware logo shows a subtle texture-filtering artifact
+  (the Nintendo logo and legal page are clean). Cosmetic only. (D75)
+- **`All unlocked` is experimental**: the fresh-install corruption case is
+  fixed, but saves made while it is on are not guaranteed recoverable by
+  switching it off — complete a level normally first, and back up
+  `data/ge007.eep` before enabling it. (D387)
+- No macOS or ARM support. Keyboard/mouse rebinding shipped in v0.4.0;
+  controller-button rebinding is not supported yet.
