/*
 * styles.css — Stair Budget Tool
 * ==================================
 *
 * LAYOUT CONCEPT
 *   A working tool laid out like a shop drawing: inputs on the left, the live
 *   "drawing sheet" (plan view + title strip) on the right with the estimate under
 *   it. Sections are separated by thin rules, not cards. Below 900px everything
 *   stacks in one column in this order: PLAN first (compact), then INPUTS, then the
 *   ESTIMATE, because the plan is the main feature.
 *
 *   SHARED LOOK WITH STEEL SIZE ROLODEX — KEEP IN SYNC.
 *   The tokens (colours, fonts), header, inputs, buttons and switch mirror the
 *   Rolodex app so the two tools feel like one product. If you change one of those
 *   in either app, change it in the other too.
 *
 * HOW IT CONNECTS
 *   index.html uses these classes; js/app.js only toggles the `hidden` attribute,
 *   writes text and restores each section's `open` state. js/plan.js reads the
 *   --plan-* tokens below inside the SVG.
 *
 * HOW TO EDIT
 *   - Colours: change the tokens in section 1 only. Component rules never use
 *     literal colours, so light, dark and print all follow.
 *   - Plan colours: the --plan-* tokens (light and dark blocks).
 *   - Column widths / breakpoint: section 4 (900px breakpoint).
 *   - Collapsible input sections (<details class="section">, summary heading,
 *     .section-sum text shown only when collapsed, .chevron): section 5.
 *   - Theme: data-theme="light" | "dark" on <html>, set by the inline script in
 *     index.html and the "Dark mode" switch (localStorage key 'theme').

   12. PRINT  — exactly ONE Letter page (docs/ARCHITECTURE.md §5 "Print")
   Order on paper: compact header · plan sheet · estimate (total + summary,

   Height budget (10in of printable height): header ~0.5in, plan 3.4in + title
   strip, estimate ~4.3in (16 table rows, incl. Deck, Finish, Freight, PST), small print
   ~0.3in. The spare height is what the warnings list uses when it shows up.

   TO GIVE THE PLAN MORE OR LESS ROOM: change --print-plan-h below. Lower it
   freely. 3.4in leaves room for every warning to show; with no warnings up to
   ~5in fits. The svg uses preserveAspectRatio
   "meet", so any drawing (25-tread L, 30-tread straight run…) scales down to fit
   that box instead of overflowing. If you add table rows, warnings or make the
   plan taller, re-check that print preview still shows one page.
