Devlog 11: Modular Display Mode Architecture and Layout Jitter Resolution

Feature Implementation & State Persistence

• Introduced a feature toggle layout inside the sidebar control node, offering real-time transitions between comprehensive chronological breakdowns and solitary metric configurations.
• Wired state persistence modules utilizing the local browser data subsystem (localStorage) to preserve client display configurations across session cycles and application reboots.
• Updated the data ingestion routing logic (loadInitialState) to safely aggregate user layout states without stepping over parameter strings delivered via URL fragment references.

Precision Calculation & Dynamic Interface Masking

• Integrated an isolated decimal extraction calculation routine within the interval processing tree (updateTimer) dedicated to managing strict single-unit tracking parameters.
• Configured programmatic style visibility switches across atomic timer components, enforcing clean element masking on non-applicable duration counters when single-unit modes trigger.

Typographic Stabilization & Layout Shifting Mitigation

• Corrected a severe layout jitter anomaly inside flexible grid clusters caused by variable font character dimensions shifting container boundaries during fast string state invalidations.
• Implemented font-variant-numeric: tabular-nums to enforce strict monospaced numeral allocation, keeping external box dimensions static regardless of structural text mutations.
• Introduced a dynamic responsive structural modifier block (.mode-single) to adjust component paddings, implement generous baseline tracking, and elevate text sizing bounds when processing simplified metrics.
