* chore(studio): upgrade Tailwind CSS to v4 through the Vite plugin
Studio moves from Tailwind 3.4 to 4.3.3, loaded by @tailwindcss/vite instead
of PostCSS. The JS config becomes an @theme block in studio.css carrying the
same studio.* and panel.* colors, with explicit @source globs so the gitignored
data/projects tree is never scanned.
The official upgrade tool renamed the utilities, but it rewrites bare words
inside any string, so its edits to event names, CSS property names, filter
function names, status enum values and prose were reverted by hand.
Nothing in Studio relied on the v3 default border color, ring width or ring
color, so the tool's compatibility shim was dropped rather than kept.
* chore(studio): note the duplicated palette between theme css and preset
* fix(studio): keep the pointer cursor on buttons after the Tailwind v4 upgrade
v4 preflight dropped the pointer cursor on enabled buttons, so add it back in
one base rule. Also migrate the last outline-none to outline-hidden.
* fix(studio): keep the Renders Export button at its shipped 14px size
* chore(studio): allow the tailwind v4 config deletions in the deletion guard
