+# TASK-212 - Add killfeed weapon icon background
+
+## Goal
+
+Anadir una placa visual clara detras de los iconos de arma negros en la feed de bajas de `partida-actual`, sin modificar ningun SVG, asset fisico ni mapping de armas, para mejorar legibilidad dentro de la estetica militar sobria del proyecto.
+
+## Context
+
+En `frontend/assets/js/partida-actual.js`, la feed de bajas renderiza iconos mediante `renderKillFeedWeaponIcon()`. Actualmente esa funcion devuelve directamente un `<img class="current-match-killfeed__weapon-icon" ...>`.
+
+Despues de `TASK-209`, `resolveKillFeedWeapon()` prioriza `globalThis.HLL_VIETNAM_CURRENT_MATCH_WEAPON_ICONS`, definido en `frontend/assets/js/current-match-weapon-icons.js`, que apunta a iconos negros desde `./assets/img/weapons/black/`. Como esos SVG tienen fondo transparente, en la feed se ve la silueta negra sin una base clara que la separe del fondo del panel.
+
+La implementacion debe envolver el icono en un contenedor visual estable, mantener el fallback `?` dentro de la misma placa o con estilo compatible, conservar el texto del arma visible y no alterar la fila de forma exagerada ni romper responsive.
+
+Preserve the current product identity: Spanish-speaking HLL Vietnam community, military/Vietnam/tactical/sober visual direction and controlled repository evolution.
+
+## Steps
+
+1. Revisar los archivos listados en `Files to Read First`, confirmando como se resuelve el icono, donde se renderiza el arma y donde viven los estilos reales del kill feed.
+2. Modificar `renderKillFeedWeaponIcon()` para envolver el icono en un contenedor especifico, por ejemplo `current-match-killfeed__weapon-icon-frame`.
+3. Mantener el fallback `?` dentro de la misma placa o con un estilo visual equivalente, sin cambiar el mapping de armas.
+4. Anadir o ajustar CSS para dar al contenedor:
+   - fondo blanco o crema militar claro
+   - borde sutil
+   - `border-radius`
+   - `padding`
+   - tamano estable
+   - `display: grid` y `place-items: center`
+5. Mantener el `<img>` con `object-fit: contain` y sin deformacion.
+6. Validar sintaxis JS, revisar visualmente `partida-actual` en local y documentar exclusiones.
+
+## Files to Read First
+
+- `AGENTS.md`
+- `ai/repo-context.md`
+- `ai/architecture-index.md`
+- `frontend/partida-actual.html`
+- `frontend/assets/js/partida-actual.js`
+- `frontend/assets/js/current-match-weapon-icons.js`
+- `frontend/assets/css/historico.css`
+
+## Expected Files to Modify
+
+- `ai/tasks/in-progress/TASK-212-add-killfeed-weapon-icon-background.md`
+- `frontend/assets/js/partida-actual.js`
+- `frontend/assets/css/historico.css`
+
+Optional only if strictly necessary:
+
+- `frontend/partida-actual.html`
+- `frontend/assets/css/styles.css`
+
+## Constraints
+
+- Keep the change minimal.
+- Preserve HLL Vietnam project identity.
+- Do not introduce unnecessary frameworks or dependencies.
+- Do not overwrite repository-specific context with generic platform template text.
+- No ejecutar `ai-platform run`.
+- No tocar `backend/` ni endpoints.
+- No tocar `frontend/assets/img/weapons/`.
+- No tocar SVGs.
+- No modificar imagenes fisicas.
+- No cambiar el mapping de armas.
+- No reactivar Elo/MMR.
+- No reintroducir Comunidad Hispana #03.
+- Mantener compatibilidad con apertura directa en navegador y responsive.
+
+## Validation
+
+Before completing the task ensure:
+
+- `renderKillFeedWeaponIcon()` envuelve el icono en un contenedor visual claro y estable
+- los iconos negros se ven sobre una caja clara/blanca integrada con la estetica militar de la feed
+- el fallback `?` usa la misma placa o un estilo compatible
+- el `<img>` mantiene `object-fit: contain` y no se deforma
+- la fila del kill feed no crece de forma exagerada
+- el texto del arma sigue visible
+- se ejecuta:
+
+```bash
+node --check frontend/assets/js/partida-actual.js
+node --check frontend/assets/js/current-match-weapon-icons.js
+```
+
+- se realiza inspeccion visual local de `partida-actual`
+- se confirma que no se tocaron:
+  - `backend/`
+  - `frontend/assets/img/weapons/`
+  - SVGs
+  - `ai/system-metrics.md`
+- `git diff --name-only` matches the expected scope
+- no unrelated files were modified
+
+## Outcome
+
+Documentar:
+
+- que cambio se hizo en `renderKillFeedWeaponIcon()`
+- que clases CSS nuevas o ajustadas se anadieron para la placa del icono
+- como queda tratado el fallback `?`
+- validacion sintactica y visual realizada
+- confirmacion explicita de que no se tocaron backend, assets de armas, SVGs, imagenes fisicas, Elo/MMR ni Comunidad Hispana #03
+
+Result:
+
+- Updated `frontend/assets/js/partida-actual.js` so `renderKillFeedWeaponIcon()` now wraps both the `<img>` and the `?` fallback inside `current-match-killfeed__weapon-icon-frame`.
+- Updated `frontend/assets/css/historico.css` with a stable light cream weapon plate and adjusted icon/fallback sizing so black transparent SVGs remain readable without changing the weapon mapping.
+- Kept the weapon label visible below the icon plate and preserved the current kill feed structure and responsive behavior.
+
+Validation performed:
+
+- PASS: `node --check frontend/assets/js/partida-actual.js`
+- PASS: `node --check frontend/assets/js/current-match-weapon-icons.js`
+- PASS: visual local inspection using temporary headless-browser screenshots for desktop and mobile widths confirmed:
+  - black weapon icon visible over a light plate
+  - fallback `?` rendered inside the same plate
+  - weapon text still visible
+  - no exaggerated row growth
+  - responsive layout remained usable
+- PASS: reviewed `git status --short --untracked-files=all`
+- PASS: reviewed `git diff --name-only`
+
+Scope confirmation:
+
+- No backend file or endpoint was touched.
+- No weapon asset, SVG or physical image was modified.
+- No weapon mapping or icon path was changed.
+- `ai/system-metrics.md` was not touched by this task.
+- Elo/MMR was not reactivated.
+- Comunidad Hispana #03 was not reintroduced.
+- No push was made.
+
+## Change Budget
+
+- Prefer fewer than 5 modified files.
+- Prefer changes under 200 lines when feasible.
+- Split the work into follow-up tasks if limits are exceeded.
