/* ================================================================
 * SPACESENSE MODERNIZATION LAYER — Commit 6: Palette lift
 * ----------------------------------------------------------------
 * Shifts the surface palette from near-black to a navy-dominant set.
 *
 *   Base    #0b0f14 → #131e2a   (deeper navy, not black)
 *   Panel   #111822 → #243443   (lifted panel surface)
 *   Panel2  #0f1620 → #1c2a38   (slight contrast for gradient ends)
 *   Line    #223041 → #3a526b   (visible navy border)
 *   Muted   #9fb0c0 → #b3c2d1   (slightly higher contrast on lighter bg)
 *   Muted2  #7f94a7 → #94a5b8
 *
 * Strategy: override the :root tokens at file tail AND retarget the
 * highest-visibility selectors that hardcode the old dark values
 * (body gradient, topbar, panels, buttons, segmented controls,
 * KPI bar, dropdowns, modal cards, scenario badge, scrollbar
 * thumbs). Translucent `rgba(0,0,0,X)` overlays elsewhere now read
 * as gentle tonal modifiers on top of the navy base — no change
 * needed for those.
 *
 * To revert: delete from this banner to the matching
 * `=== END MODERNIZATION COMMIT 6 ===` line.

/* ================================================================
 * SPACESENSE MODERNIZATION LAYER — Commit 10: Hero-the-vacancy
 * ----------------------------------------------------------------
 * Three additions:
 *
 *  A. Annual Saving primary KPI dial — brand-yellow value, sits
 *     between Unallocated and Active Floors. JS in app.js handles
 *     fallback states (baseline plan, missing data, pre-run).
 *
 *  B. Vacant cell tint — cells on an optimised plan with zero
 *     chips get a yellow-hatched overlay and "VACANT" label.
 *     Overlay uses pointer-events: none so drag-drop into the
 *     cell continues to land normally; the .cell-vacant-opt class
 *     is removed automatically when a chip is dropped (renderMap
 *     re-runs and re-evaluates floorStats().used). Skipped
 *     entirely on the Existing baseline tab.
 *
 *  C. Diagnostics collapse — toggle button hides/shows the
 *     secondary KPI strip (OR Score / Solver / Conflicts /
 *     Coverage). Default = expanded; state persists in
 *     localStorage.
 *
 * To revert this commit only: delete from this banner to the
 * matching `=== END MODERNIZATION COMMIT 10 ===` line. App still
 * runs — JS reads localStorage / classList safely whether the
 * CSS is present or not.

 * SPACESENSE MODERNIZATION LAYER — Commit 12: Polish fixes
 * ----------------------------------------------------------------
 * Two real-world fixes from the first Vercel preview of Commits
 * 9–11:
 *
 *   A. Topbar wordmark was being clipped at the top because
 *      Commit 9 trimmed padding to 4px without giving the brand
 *      wordmark an explicit line-height. Adding `line-height: 1.2`
 *      to .brand and bumping topbar top-padding to 8px restores
 *      breathing room while still being much slimmer than the
 *      pre-modernization 14px.
 *
 *   B. (No CSS change; pure JS fix in app.js this commit.) The
 *      "VACANT · N FLOORS" pills and "X floors freed" sub were
 *      appearing on the Existing baseline tab because Commit 11
 *      checked `activePlanRunId === EXISTING_PLAN_ID` instead of
 *      `!activePlanRunId || === EXISTING_PLAN_ID`. Before any
 *      optimiser run, activePlanRunId is null (default), not
 *      EXISTING_PLAN_ID. The plan-tab UI already treats null as
 *      "Existing active" — we now match that semantics in
 *      renderKPIBar + renderMap.

 *       Lighter inset shadow on the cell wash.
 *   #2  Topbar wordmark clipping — more aggressive padding +
 *       overflow:visible. Wordmark now has real breathing room.
 *   #3  KPI dial icons bumped from 14→18px (primary) and 12→16px
 *       (secondary) so they read on a 1440p+ monitor.
 *   #4  Cell header simplified — F-label dropped, fill-bar dropped,
 *       text reads "0 / 709 sqm" only. (JS change in app.js.)
 *   #6  Menubar dropdown-toggle icons removed (menu items now
 *       text-only). The Run Optimizer sparkle icon is preserved.
 *   #16 Sub-menu visually distinct from menu — softer fill,
 *       brighter left border, larger indent.
 *
 * To revert this commit only: delete from this banner to the

/* ================================================================
 * SPACESENSE MODERNIZATION LAYER — Commit 14: Round-1 corrections
 * ----------------------------------------------------------------
 * Four corrections from second-pass review:
 *
 *   #4  Re-add the colored fill bar in expanded map cells. Commit
 *       13 removed it together with the F-label; user wanted only
 *       the redundant text removed, not the visual occupancy
 *       gauge. (JS change in app.js.)
 *   #16 corrected — the "menu vs sub-menu" feedback was about the
 *       *Reports overlay left sidebar* (Inputs / Outputs / Analysis
 *       section labels vs report-item buttons), not the topbar
 *       dropdown submenus. Lift the visual distinction with a
 *       brighter accent + extra spacing.
 *   #17 Compact-mode map cells: remove the floor-name + stats
 *       header (the left-column floor label already shows the
 *       F-label; the bar tooltip carries the stats). JS change in
 *       app.js.
 *   #18 Building column header "VACANT · N FLOORS" pill removed
 *       (revert of Commit 11 piece). Cell-level VACANT badges
 *       + Active Floors KPI already convey it. JS change in
 *       app.js. CSS for .building-vacant-pill is kept harmless
 *       (no element renders it).
 *
 * To revert this commit only: delete from this banner to the
 * matching `=== END MODERNIZATION COMMIT 14 ===` line.

 * SPACESENSE MODERNIZATION LAYER — Commit 16: Round-2a
 * ----------------------------------------------------------------
 * Two fixes:
 *
 *   #5 Open Scenario modal — soften card actions. Load button no
 *      longer "screams" yellow on every card; only the primary
 *      action of the active card uses brand-yellow. Delete button
 *      becomes a quiet text/border button (was filled red). Card
 *      padding/spacing tightened. (TEST_-prefix filter is in
 *      app.js renderCloudTabContent — Commit 16.)
 *
 *   #7 Allocations table — header lock-all checkbox replaces the
 *      "Unlock all" button. Standard select-all pattern (checked /
 *      indeterminate / unchecked). Styled to read as a single
 *      affordance next to the "Lock" column label. (Wiring in
 *      app.js renderLedger — Commit 16.)

 *      visible rows. Excel-style.
 *
 *   #11 — click-to-sort headers and per-column filters applied to
 *      Floor utilization + Building utilization tables (in
 *      addition to Allocations).
 *
 * To revert this commit only: delete from this banner to the

/* ================================================================
 * SPACESENSE MODERNIZATION LAYER — Commit 22: Scorecard V2 parity
 * ----------------------------------------------------------------
 * Five surgical additions to V2 to close the "critical exec-summary"
 * gap vs the legacy Value Scorecard. Full detail (vacancy breakdown
 * per building/floor/block, NPV sensitivity grid, per-floor meeting-
 * seats drill-down, etc.) stays in the legacy panel.
 *
 *   1. Buildings freed → 4th card in Physical Impact (CSS: grid bump)
 *   2. Wasted Space Cost (before/after) → row under Utilisation bars
 *   3. Vacancy Decomposition headline → new compact 2-card section
 *      between Utilisation and Coverage
 *   4. Total one-time savings / costs → small rollup at bottom of
 *      the Cost Breakdown left card
 *   5. Collaboration improvement % → small delta pill on Coverage
 *      dial #3
 *
 * To revert: delete from this banner to the matching
 * `=== END MODERNIZATION COMMIT 22 ===` line and revert the
 * corresponding edits in app.js renderScorecardV2.

 * SPACESENSE MODERNIZATION LAYER — Commit 23: Scorecard clarity
 * ----------------------------------------------------------------
 * "Comparing" header chips on both Value Scorecard and Scorecard V2
 * to make it explicit which two plans are in the picture:
 *   Reference · Existing AS-IS  ↗   vs   Active · Cost-first @ 02:43
 * Reference chip is clickable — switches the map to the Existing tab.
 *
 * Paired with a JS fix that ensures both scorecards re-render when
 * the user switches the map to Existing (the legacy code only called
 * renderAll, leaving stale scorecard data showing).
 *
 * To revert: delete from this banner to the matching
 * `=== END MODERNIZATION COMMIT 23 ===` line.

 * Reflows the Sensitivity tab from 3 stacked sections (Weight Tuner,

 *   Row 1 — full-width Run Summary strip (OR Score · Solver · Conflicts

 *   Row 3 — 2-col DIAGNOSTICS (Constraint Impact | Unmet Demand) with
 *           big ✓ empty states when nothing's wrong
 *
 * Pure JS template restructure + this CSS. The existing tuner sliders,
 * preset selector, Save / Save & Re-run buttons, and the What-If
 * section appended afterwards keep all their IDs/classes and event

 * SPACESENSE MODERNIZATION LAYER — Commit 27: Constraints / Sensitivity
 *                                              cleanup (PR-A)
 * ----------------------------------------------------------------
 * Structural fix: conflict diagnostics move from the Constraints tab
 * (INPUTS section) to the Sensitivity tab's Constraint Impact card
 * (ANALYSIS section), where they belong as post-run outputs.
 *
 *   - Constraints tab gets a compact summary banner ("3 conflicts —
 *     view in Sensitivity →") instead of the rich cards
 *   - Each rule row that has conflicts gets a `⚠ N` pill in its ID
 *     cell + a left-edge accent
 *   - Sensitivity's Constraint Impact card now embeds the individual
 *     violation cards below the type-summary table
 *   - showViolations() now jumps to Sensitivity (not Constraints)
 *
 * Functionality not touched: saveConstraintAdjField, deleteConstraintAdj,
 * addConstraintAdj, buildViolationDiagnosis all unchanged. The KPI bar's
 * Conflicts dial still uses showViolations(); just lands in a different
 * tab now.
 *
 * To revert: delete from this banner to the matching
 * `=== END MODERNIZATION COMMIT 27 ===` line and revert the
 * renderConstraints + renderSensitivity + showViolations edits in
 * app.js.

 *                                              detail polish
 * ----------------------------------------------------------------
 * Two fixes:
 *   1. The violation cards (moved here in Commit 27) lived INSIDE the
 *      Constraint Impact card in the left column of the 2-col grid.
 *      With many violations this made the left col much taller than
 *      the right (Unmet Demand) → ugly empty space on the right.
 *      Now they live in a separate full-width "Conflict Detail" card
 *      BELOW the 2-col Diagnostics grid.
 *   2. The legacy .violation-card style (Phase-2 era) didn't blend
 *      with the new .sens-v2-card aesthetic. Inside the new container
 *      we restyle them — gradient surface, rounded corners,
 *      brand-yellow accent for HARD, amber for SOFT.
 *
 * To revert: delete from this banner to the matching
 * `=== END MODERNIZATION COMMIT 29 ===` line + revert the
 * conflictDetailHtml extraction in renderSensitivity.

 * Adds 3 new cards to the Constraints page:

 *   - Coverage Standards — pure read-only viewer with a READ-ONLY

 *
 * No new "Add" forms in this PR — direct DB insert still required.
 * UI for Add comes in a follow-up.

 * ----------------------------------------------------------------
 * Two changes:

 *      hard-only (Tranche 5-γ removed weight + is_hard columns;
 *      adjacency_type CHECK restricts to SAME_FLOOR / SAME_LEVEL /
 *      SAME_BUILDING). UI dropped weight slider + HARD/soft cell,
 *      and ADJ_TYPES tightened to the 3 valid values.
 *
 *   2. Inline "+ Add Rule" affordance INSIDE the Adjacency Rules
 *      card. The standalone "Add New Constraint" card at the bottom
 *      of the page is removed. Save requires an explicit confirm()
 *      dialog so an accidental click can't write to the DB.
 *

/* === MODERNIZATION COMMIT 35 ===
 * Inline + Add for Colocation, Location, Capacity Buffer cards
 * --------------------------------------------------------------
 * Completes the inline-Add pattern across the Constraints page —
 * the Adjacency card got it in Commit 33; this commit applies the
 * same UX (collapsed "+ Add Rule" bar, expanding form panel,
 * explicit confirm() before DB write) to the other three cards.
 * Reuses the existing `.cst-inline-add-bar`, `.cst-inline-add-btn`,
 * `.cst-inline-add-form` styles from Commit 33 — this block just
 * adds the per-group "+ Add Member" button styling for Colocation
 * (the only new visual primitive in this commit).
 *
 * To revert: delete from "MODERNIZATION COMMIT 35" header to the
 * `=== END MODERNIZATION COMMIT 35 ===` line. Restoring the
 * builders / handlers requires reverting the matching block in app.js.

 * SPACESENSE MODERNIZATION COMMIT 37 — Back-to-overview bridge
 * ----------------------------------------------------------------
 * Two affordances that let a visitor return from the tool to the
 * landing page at `/`:
 *   1. The brand wordmark in the top-left is now wrapped in an
 *      anchor (display: contents preserves the existing grid).
 *      Clicking SPACESENSE → home.
 *   2. A small "← Overview" pill in the topbar between the brand
 *      and the menubar — explicit affordance for first-time
 *      visitors who don't know the wordmark is clickable.
 *
 * Why: after PR #314 made the landing live at `/`, the tool became
 * a one-way trip. Faculty exploring after the seminar had no way
 * to get back to the framing context. This is the smallest possible
 * bridge.
 *
 * To revert: delete from this banner to the matching
 * `=== END MODERNIZATION COMMIT 37 ===` line.
