Changes in version 0.3.2 (2026-10-09)                  

New Features

  - Multi-Page Growth Curve PDF Export: Added
    export_batch_growth_curves_pdf() to export comprehensive,
    publication-ready growth curve PDFs for all strains across all
    plates in a batch:
      - Generates one page per strain with facet panels for each plate
        and individual trajectories for replicate wells.
      - Controls (WT, Blank, etc.) are rendered first, followed by
        mutants alphabetically.
      - Uses dynamic per-page y-axis scaling with small margins (~8%)
        fitted to the strain's own data range, preventing blank upper
        space for slow-growing or low-yield strains.
  - Batch Overview Export UI: Added a dedicated export card in
    mod_batch_overview allowing interactive downloading of Raw OD or
    Corrected OD multi-page growth curve reports with a live Shiny
    progress indicator.

Improvements & Bug Fixes

  - Data Fidelity (No Normalization):
      - Raw OD mode outputs unmodified absorbance readings directly from
        instrument assays.
      - Corrected OD mode performs direct blank subtraction ($OD_{raw} -
        OD_{blank_median}$) without clipping, ceiling, or artificial
        floors (e.g. pmax(..., 0.01)). Negative blank-corrected values
        are preserved accurately.
      - Retains all control wells (Blank, Empty) across both modes.

                 Changes in version 0.3.1 (2026-10-08)                  

Quality Control & Plate Validation

  - Automated Failure Detection: compute_metrics() now flags plate QC
    failure if all blank wells are contaminated or if all wild-type (WT)
    control wells fail to grow.
  - Manual QC Override: Users can inspect and toggle a plate's status
    (PASSED / FAILED) directly within the Plate Card interface.
  - Batch Quarantine: Added validate_batch_plates() to forbid including
    FAILED plates in downstream batches.
  - Layout Consistency Enforcement: validate_batch_plates() verifies
    that all plates within a single batch share an identical 384-well
    layout.

Scoring & UI Enhancements

  - Intra-Plate Scoring Gating: Dynamic UI validation prevents selecting
    the intra-plate (NoDrug_Wells) strategy when layouts lack _NoDrug
    control wells.
  - Plate Card Recalculation: Plate edits automatically trigger metric
    and QC recomputation.
  - Navigation: Restored and activated Batch Overview and Scoring
    dashboard menu items.

                 Changes in version 0.3.0 (2026-08-09)                  

Initial Architecture & Core Features

  - S4 Data Architecture: Core classes Plate, Batch, and persistent
    container PlateRegistry.
  - Tecan Reader & Layout Parsing: Built tidy parsers for Tecan OD raw
    matrix outputs and 96/384-well plate layouts.
  - Staining Jump Detection: Automatic staining detection
    (detect_staining_jump()) for crystal violet biofilm assays.
  - Interactive Shiny Dashboard: Golem-structured modules for plate
    browsing, batch building, quality control visualization, and
    chemo-genomic interaction scoring.
