Restyle the Ecualizador settings screen to the new visual language while keeping the equalizer at 5 bands (spike-resolved, Engram id 2498 - band count is device-reported via just_audio's AndroidEqualizer, not app-chosen; the approved mockup's 7 sliders would silently no-op on typical hardware). - Restyle EcualizadorWidget in place: strip its internal title + preset chip row (the pushed screen's header now carries the title), add a habilitado parameter that greys/disables every slider when EQ is off. Widen PresetsEcualizadorWidget additively (personalizados param) so custom presets can join the chip row without a second implementation. - Add servicio_presets_personalizados.dart (new file, own SharedPreferences key eq_custom_presets_v1) for custom EQ preset persistence - kept out of servicio_ecualizador.dart, which has an empty-git-diff success criterion for this change. preset_ecualizador.dart is unchanged: a custom preset is just a PresetEcualizador with a user-supplied name. - Extend EstadoEcualizador with presetsPersonalizados, guardarPresetPersonalizado (validates non-empty name), eliminarPresetPersonalizado. The load is a new explicit cargarPresetsPersonalizados(), deliberately NOT folded into cargarPersistido(): that method is exercised ~30 times by estado_ecualizador_test.dart (protected, must stay unmodified) via Fakes only, with no SharedPreferences awareness in that file. - Build out the Ecualizador screen body: base-vs-per-station explainer banner, a "Salida activa" row surfaced on the main screen (previously Advanced-only), an "Emisoras con ajuste propio" drill-down sourced from the existing presetsPorEmisora map, and a "Guardar como preset" action. New coverage lives in new files rather than touching the three protected EQ test files: ecualizador_widget_test.dart (component-level, did not exist before this commit), servicio_presets_personalizados_test.dart, and estado_ecualizador_presets_personalizados_test.dart. servicio_ecualizador.dart, servicio_audio.dart and the three protected EQ test files keep an empty git diff. Full suite: 713/713 green (2 skipped, unchanged), up from 682. size:exception - realized 1,954 changed lines (25 files, plus this docs update) against the 400-550 forecast: lib/ + ARB alone is ~650 lines, near the top of the forecast band by itself since this WU also had to build out a screen body WU3a only stubbed; the rest is 4 test files (675 lines) and 11 new ARB keys regenerating 13 lib/l10n/gen files (~546 lines) - the same pattern every prior work unit in this branch has hit. Not splittable: WU14 reuses this unit's editor component by exact runtime type and cannot begin until this lands as a whole.
