   Firstlight UI — clean and minimal (content-preserving)
   --------------------------------------------------------------------------
   This file is loaded LAST (see app/layout.tsx) and is the only place a
   visual decision should now live. It supersedes the earlier warm,
   orange-heavy layer in this same file.

   It changes LOOK only:
   - no class names, text, routes, markup, or JavaScript behaviour changes
   - no content, copy, pricing, limits, or feature changes

   Clean and minimal, in practice, means:
   - near-white background, white cards, one thin neutral border
   - almost no shadow, no gradients, no competing colours
   - ink for primary actions, the brand orange only as a small accent
   - more whitespace, lighter type weights, one consistent radius

   11. Fixes 2026-10-28 — sidebar, alignment, launch button, topbar
   --------------------------------------------------------------------------
   Root causes found in the earlier sheets, not in this file:
   - The topbar was a floating pill, centred by margin + translateX,
     while the feed used different left paddings (28px heading,
     24px post list), so the middle never lined up with the topbar.
   - The launch button was hidden at <=980px (display:none in
     refresh.css) and forced to icon-only at <=760px (font-size:0 in
     v3.css, with the text node inheriting that size).
   - The left rail stacked brand, nav, a compose button, extra
     tools, a beta note, appearance links, and a profile card, each
     with its own size, weight, and spacing.
   Fixes below are visual only. No button, link, or section is
   removed; secondary rail items are quieted, not hidden.
   One gutter is used everywhere: 28px desktop, 24px tablet, 16px
   mobile, so topbar, heading, filters, and posts share a left edge.
