+## Widescreen battle layout
+
+Options **BATTLE LAYOUT** picks the battle screen's composition: **OG**
+(the default: the original 160×144 arrangement, unchanged) or **WIDE**,
+which gives battles a 304×144 native-pixel surface and a Gen 3-style
+arrangement on it:
+
+- the foe's status box upper left, the foe's picture upper right;
+- the player's picture lower left, the player's status box lower right,
+  with a longer HP bar and the numeric HP under it;
+- a full-width message window;
+- a split "What will X do?" prompt / 2×2 command window;
+- a 2×2 move menu, navigated with all four directions, with a PP and type
+  panel attached to its right.
+
+Only the composition changes. Pictures, palettes, HP-bar colors, font
+pages, window borders, sounds, animations, timing and every battle rule
+stay the engine's, so a COLORS mode or an asset mod still owns the look.
+Each side's picture keeps its original pixels and placement math and is
+composited into its own region of the wider battlefield -- nothing is
+scaled or squeezed -- and animations, which are authored in the original
+160-pixel space, shift as one rigid group onto whichever side they play
+on. The whole screen is drawn at the window's integer fit scale for the
+wider surface, so a 304-pixel screen is drawn a step smaller than a
+160-pixel one in the same window.
+
+The wide surface is live only while the battle itself is the screen on
+top: a party menu, the bag or a nickname prompt is a 160×144 screen and
+brings the classic surface back with it.

+## Save editor (bundled, reachable from the launcher)
+
+The save editor ships inside every build instead of being a developer-only
+script, and the launcher's SAVE SLOT card grows an **Edit** label next to
+Delete on every slot that actually holds a save. Edit suspends the
+launcher, opens that slot's file in the editor, and **Close** hands the
+process back to the launcher with the slot list re-read (a rename, a badge
+or a dex change shows up on the row immediately). Unsaved edits arm a
+confirm first, so leaving cannot lose work. `love . --editor` still opens
+it standalone, where Close quits instead; `--save <path>` points it at any
+file, and a save can be dragged onto the window.
+
+The editor now wears the launcher's visual language - the same navy radial
+field, 16px translucent cards, tri-colour version rail and green/yellow/red
+semantics - so the two windows read as one app. Six tabs:
+
+- **Party**: the roster with sprites, HP bars and level chips on the left,
+  and the mon inspector permanently docked on the right instead of floating
+  over the list. Species, level, DVs and moves all round-trip through the
+  Gen 1 formulas, so the inspector can never show illegal stats.
+- **Boxes**: the 12 PC boxes as a 5x4 grid with a fill meter per box and a
+  party dock, so deposit and withdraw live in one place. Empty slots are
+  clickable and create a mon there.
+- **Items**: money, a searchable item picker (replacing the arrows that
+  cycled one id at a time through ~250 items), the 20-slot bag, PC storage
+  with no slot cap, and the eight badges as toggle chips.
+- **Events**: flags, defeated trainers, taken items and per-map object
+  toggles, with a real filter field and a two-column paged grid.
+- **Map**: any map rendered with the game's own renderer, warps followable,
+  and the player / lastHeal / lastOutdoor spawn points settable by clicking
+  a cell. Setting lastOutdoor on a map the game would not accept as an
+  outdoor source is refused with the reason.
+- **Dex**: seen / owned completion meters and a four-column grid; owning
+  implies seen and un-seeing clears owned, exactly as the game requires.
+
+Two rules run through all of it. Every mutation goes through one funnel
+that sets the dirty flag and writes the status line together, so nothing
+changes silently and no branch can quietly no-op - "Party is full", "Bag is
+full", "click a cell first" all say so. And every destructive verb (Remove,
+Release, Clear all, Wipe dex) arms on the first click and commits on the
+second, relabelling itself to `Confirm?` in between.
+
+A validation pill in the tab rail mirrors what the running game would
+quarantine on load; clicking it jumps to the tab holding the first problem.
