/* TSI Surgical Instrument Catalog — Phase 3
 *
 * Ported from prototype\index.html (approved by Joe 7/24: "I want it to look exactly like this").
 * Values come straight out of prototype\STYLE-GUIDE.md. Do not "improve" the palette, the
 * spacing or the radii — this is a signed-off design, not a starting point.
 *
 * Deliberate changes from the prototype, and only these:
 *   1. Inter is loaded from Google Fonts (prototype rendered in Segoe UI, Windows-only).
 *   2. The yellow prototype banner and "Simulate logged-in" checkbox are gone (review aids).
 *   3. Row grid is capped at 3 columns and collapses cleanly below 560px so the page body
 *      never scrolls sideways.
 *   4. Sidebar / modal / quote panel gain mobile + tablet layouts the prototype never had.
