Code Review Summary — relojlcd_v56 This update is an internal refactor plus one small visual fix. No new features, no new permissions, no network calls, no new dependencies. All changes preserve existing functionality and visual appearance. 1. Static data moved to module level The theme color map and the flicker-opacity thresholds are now constants (THEME_MAP, FLICKER_THRESHOLDS) declared outside the class, instead of being rebuilt on every style update. 2. Extracted duplicate logic Shadow calculation was duplicated between the clock label and the alarm dot. It now lives in a single _calculateShadow() method used by both. 3. Split a large method into smaller ones The ~140-line _updateStyle() is now a short method that delegates to focused helpers: _getStyleConfig(), _getTheme(), _updateShadowLabelVisibility(), _buildContainerStyle(), _buildClockStyle(), _buildShadowStyle(), _buildBaseStyleProps(), _calculateBoxShadow(), _applyStyles(). 4. Simplified flicker logic Replaced three near-identical nested if/else chains (one per color type) with a clean data-driven lookup against FLICKER_THRESHOLDS. 5. Separated UI from interaction logic Drag-and-drop and right-click-to-open-preferences handling extracted to _setupDragHandlers(), keeping indicator construction separate from event handling. 6. Extracted time formatting Time/date string formatting logic moved to _formatTime() for clarity and reuse. 7. Small visual fix Added align-self: center to the .reloj-lcd-alarm-dot rule in stylesheet.css so the alarm indicator dot is properly centered within its container. 8. Version bump metadata.json updated from 55 to 56 to reflect the code changes. Every widget created in enable()/its helpers (_indicator, _container, _clockContainer, _clockLabel, _shadowLabel, _alarmDot, _inputGuard, the drag grab) is destroyed and explicitly set to null in disable(), one statement per object. Every GLib main loop source (clock, flicker, init, alarm, blink) has a matching, explicitly-named removal helper (_removeClockTimeout(), _removeFlickerTimeout(), etc.) called both in disable() and immediately before the same field is reassigned, so no source is ever overwritten without being removed first. This explicit, one-property-per-statement style was kept intentionally (rather than folding it into a generic loop/dynamic-property helper) so that static analysis tools can trace each create/destroy and add/remove pair directly.
